Abstract

The inventors have isolated novel genes with a high homology to theT. lanuginosuslipase gene and are thus well suited for use in gene shuffling. Accordingly, the invention provides a method of generating genetic diversity into lipolytic enzymes by family shuffling of two or more homologous genes which encode lipolytic enzymes. The DNA shuffling technique is used to create a library of shuffled genes, and this is expressed in a suitable expression system and the expressed proteins are screened for lipolytic enzyme activity. The expressed proteins may further be screened to identify lipolytic enzymes with improved properties. The invention also provides a polynucleotide comprising a nucleotide sequence encoding a lipolytic enzyme and a lipolytic enzyme (a polypeptide with lipolytic enzyme activity).

Description

FIELD OF THE INVENTION
• The present invention relates to a method of generating diversity into lipolytic enzymes by the use of the so-called family shuffling of homologous genes. The invention also relates to polynucleotides for use in the method, and to lipolytic enzymes encoded by the polynucleotides.[0001]
BACKGROUND OF THE INVENTION
• The lipase of[0002]Thermomyces lanuginosus(also known asHumicola lanuginosa) is known to be useful for various industrial purposes such as detergents and baking (EP 258068, WO 9404035). Its amino acid and DNA sequences are shown in U.S. Pat. No. 5,869,438.
• The prior art describes the modification of the amino acid sequence of the[0003]T. lanuginosuslipase to create variants with the aim of modifying the enzyme properties. Thus, U.S. Pat. No. 5,869,438, WO 9522615, WO 9704079 and WO 0032758 disclose the use of mutagenesis of the lipase gene to produce such variants. WO 0032758 also discloses the construction of variants with the backbone fromT. lanuginosuslipase and C-terminal fromFusarium oxysporumphospholipase by PCR reaction.
• Crameri et al, 1998, Nature, 391: 288-291 discloses DNA shuffling of a family of naturally occurring homologous genes from diverse species to create diversity into proteins. U.S. Pat. No. 6,159,687 discloses shuffling of genes encoding variants of the[0004]T. lanuginosuslipase. WO 9841623 discloses shuffling of heterologous polynucleotide sequences.
• The following published sequences of lipolytic enzymes from Aspergillus have amino acid identities of 49-51% to the[0005]T. lanuginosuslipase: Lysophospholipase fromA. foetidus(EMBL A93428, U.S. Pat. No. 6,140,094), lipase fromA. tubingensis(EMBL A84589, WO 9845453), phospholipase A1 fromA. oryzae(EMBL E16314, EP 575133, JP 10155493 A) and Lysophospholipase fromA. niger(EMBL A90761, WO 98/31790).
• R. Lattmann et al., Biocatalysis, 3 (1-2), 137-144 (1990) disclose an esterase from[0006]Talaromyces thermophilus. V. W. Ogundero, Mycologia, 72 (1), 118-126 (1980) describes the lipase activity ofTalaromyces thermophilus. U.S. Pat. No. 4,275,011 and EP 258068 refer to a lipase fromThermomyces ibadanensis. B. A. Oso, Canadian Journal of Botany, 56: 1840-1843 (1978) describes the lipase activity ofTalaromyces emersonii.

• Accordingly, the invention provides a method of generating genetic diversity into lipolytic enzymes by family shuffling of two or more homologous genes which encode lipolytic enzymes. One gene encodes a lipolytic enzyme with at least 90% identity to the[0019]T. Ianuginosuslipase, and another gene encodes a lipolytic enzyme with 55-90% identity to theT. lanuginosuslipase. The DNA shuffling technique Is used to create a library of chimeric shuffled genes, and this is expressed in a suitable expression system and the expressed proteins are screened for lipolytic enzyme activity. The expressed proteins may further be screened to identify lipolytic enzymes with improved properties.
• The invention also provides a polynucleotide comprising a nucleotide sequence encoding a lipolytic enzyme and a lipolytic enzyme (a polypeptide with lipolytic enzyme activity).[0020]
• The polynucleotide may be a DNA sequence cloned into a plasmid present in[0021]E. colideposit number DSM 14047, 14048, 14049, or 14051, the DNA sequence encoding a mature peptide shown in SEQ ID NO: 3, 5, 7 or 9 or one that can be derived therefrom by substitution, deletion, and/or insertion of one or more nucleotides. The polynucleotide may have at least 90% identity with the DNA sequence encoding a mature peptide shown in SEQ ID NO: 3, at least 80% identity with the DNA sequence encoding a mature peptide shown in SEQ ID NO: 5, at least 65% identity with the DNA sequence encoding a mature peptide shown in SEQ ID NO: 7, or at least 60% identity with the DNA sequence encoding a mature peptide shown in SEQ ID NO: 9. It may also be an allelic variant of the DNA sequence encoding a mature peptide shown in SEQ ID NO: 3, 5, 7 or 9; or it may hybridize under high stringency conditions with a complementary strand of the nucleic acid sequence encoding a mature peptide shown in SEQ ID NO: 3, 5, 7 or 9, or a subsequence thereof having at least 100 nucleotides.
• The lipolytic enzyme may be encoded by a DNA sequence cloned into a plasmid present in[0022]E. colideposit number DSM 14047 or 14049, or may have an amino acid sequence which is the mature peptide of SEQ ID NO: 6 or 10, or one that can be derived therefrom by substitution, deletion, and/or insertion of one or more amino acids. The lipolytic enzyme may have an amino acid sequence which has at least 80% identity with the mature peptide of SEQ ID NO: 6 or at least 60% identity with the mature peptide of SEQ ID NO: 10. The lipolytic enzyme may further be immunologically reactive with an antibody raised against the mature peptide of SEQ ID NO: 6 or 10 in purified form, be an allelic variant of the mature peptide of SEQ ID NO: 6 or 10; or be encoded by a nucleic acid sequence which hybridizes under high stringency conditions with a complementary strand of the nucleic acid sequence encoding a mature peptide shown in SEQ ID NO: 5 or 9, or a subsequence thereof having at least 100 nucleotides.

Polynucleotides
• The polynucleotides to be used for recombination (shuffling) are two or more genes encoding lipolytic enzymes, including one with at least 90% identity and one with 55-90% identity to the[0031]T. lanuginosuslipase (SEQ ID NO: 2). The poloynucleotides differ in at least one nucleotide.
• The starting material may include the mature part of two or more (e.g. three, four or five) of SEQ ID NO: 1, 3, 5, 7 and/or 9. It may also include genes encoding two or more (e.g. three, four or five) of variants of SEQ ID NO: 2, 4, 6, 8 or 10 obtained by deleting, substituting and/or inserting one or more amino acids and/or by attaching a peptide extension at the N- and/or C-terminal. Examples of variants of the[0032]T. lanuginosuslipase are described, e.g., in U.S. Pat. No. 5,869,438, WO 9522615, WO 9704079 and WO 0032758, and similar variants can be made by altering corresponding amino acids in the other sequences.
• Any introns present in the genes may optionally be removed before the shuffling.[0033]
DNA Recombination (Shuffling)
• Shuffling between two or more homologous input polynucleotides (starting-point polynucleotides) may involve fragmenting the polynucleotides and recombining the fragments, to obtain output polynucleotides (i.e. polynucleotides that have been subjected to a shuffling cycle) wherein a number of nucleotide fragments are exchanged in comparison to the input polynucleotides.[0034]
• DNA recombination or shuffling may be a (partially) random process in which a library of chimeric genes is generated from two or more starting genes. A number of known formats can be used to carry out this shuffling or recombination process.[0035]
• The process may involve random fragmentation of parental DNA followed by reassembly by PCR to new full length genes, e.g. as presented in U.S. Pat. No. 5,605,793, U.S. Pat. No. 5,811,238, U.S. Pat. No. 5,830,721, U.S. Pat. No. 6,117,679 . In-vitro recombination of genes may be carried out, e.g. as described in U.S. Pat. No. 6,159,687, WO98/41623, U.S. Pat. No. 6,159,688, U.S. Pat. No. 5,965,408, U.S. Pat. No. 6,153,510. The recombination process may take place in vivo in a living cell, e.g. as described in WO 97/07205 and WO 98/28416.[0036]
• The parental DNA may be fragmented by DNA'se I treatment or by restriction endonuclease digests as descriobed by Kikuchi et al (2000a, Gene 236:159-167). Shuffling of two parents may be done by shuffling single stranded parental DNA of the two parents as described in Kikuchi et al (2000b, Gene 243:133-137).[0037]
• A particular method of shuffling is to follow the methods described in Crameri et al, 1998, Nature, 391: 288-291 and Ness et al. Nature Biotechnology 17: 893-896. Another format would be the methods described in U.S. Pat. No. 6,159,687: example 1 and 2.[0038]
Properties of Lipolytic Enzyme
• The lipolytic enzyme obtained by the invention is able to hydrolyze carboxylic ester bonds and is classified as EC 3.1.1 according to Enzyme Nomenclature 1992, Academic Press, Inc. It may particularly have activity as a lipase (triacylglycerol lipase) (EC 3.1.1.3), phospholipase A1 (EC 3.1.1.32), phospholipase A2 (EC 3.1.1.4), cholesterol esterase (EC 3.1.1.13) and/or galactolipase (EC 3.1.1.26).[0039]
• The thermostability was evaluated by means of Differential Scanning Calorimetry (DSC). The denaturation peak (T[0040]_d) when heated at 90 deg/hr at pH 5 is slightly above 75° C. for the lipolytic enzyme fromT. ibadanensis, compared to slightly above 70° C. for the prior-artT. lanuginosuslipase. The lipolytic enzyme fromT. ibadanensishas optimum activity at alkaline pH (similar to theT. lanuginosuslipase) and has an isoelectric point of about 4.3 (slightly lower than theT. lanuginosuslipase).
Homology and Alignment
• The best alignment of the mature parts of SEQ ID NO: 2, 4, 6, 8 and 10 is achieved by inserting a gap of one amino acid between Q249 and P/G250 of SEQ ID NO: 2, 4 and 6. This alignment defines corresponding amino acids.[0041]
• The degree of homology may be determined by means of computer programs known in the art, such as GAP provided in the GCG program package (Program Manual for the Wisconsin Package, Version 8, August 1994, Genetics Computer Group, 575 Science Drive, Madison, Wis., USA 53711) (Needleman, S. B. and Wunsch, C. D., (1970), Journal of Molecular Biology, 48, 443-45), using GAP with the following settings for polypeptide sequence comparison: GAP creation penalty of 3.0 and GAP extension penalty of 0.1.[0042]
• The determination of homology may also be made using Align from the fasta package version v20u6. Align is a Needleman-Wunsch alignment (i.e. global alignment), useful for both protein and DNA alignments. The default scoring matrices BLOSUM50 and the identity matrix are used for protein and DNA alignments respectively. The penalty for the first residue in a gap is −12 for proteins and −16 for DNA. While the penalty for additional residues in a gap is −2 for proteins and −4 for DNA.[0043]
• The homologies discussed in this specification may correspond to at least 60% identity, in particular to at least 70% or at least 80% identity, e.g. at least 90% or at least 95% identity.[0044]
Use of Lipolytic Enzyme
• Depending on the substrate specificity, the enzyme of the invention can be used, e.g., in filtration improvement, vegetable oil treatment, baking, detergents, or preparation of lysophospholipid. Thus, it may be used in known applications of lipolytic enzymes by analogy with the prior art, e.g.:[0045]
• In the pulp and paper industry, to remove pitch or to remove ink from used paper. WO 9213130, WO 9207138, JP 2160984 A, EP 374700.[0046]
• Baking. WO 94/04035, WO 00/32758.[0047]
• Detergents. WO 97/04079, WO 97/07202, WO 97/41212, WO 98/08939 and WO 97/43375.[0048]
• Leather industry. GB 2233665, EP 505920.[0049]
• An enzyme with lipase activity may be used for fat hydrolysis and for modification of triglycerides and for production of mono- and diglycerides.[0050]
• An enzyme with lipase activity may be used for interesterification of bulk fats, production of frying fats, shortenings and margarine components.[0051]
• An enzyme with phospholipase activity (A1, A2) may be used for degumming of vegetable oils and for lysophospholipid production.[0052]
Improvement of Filtration
• An enzyme with lysophospholipase activity can be used to improve the filterability of an aqueous solution or slurry of carbohydrate origin by treating it with the variant. This is particularly applicable to a solution or slurry containing a starch hydrolysate, especially a wheat starch hydrolysate since this tends to be difficult to filter and to give cloudy filtrates. The treatment can be done in analogy with EP 219,269 (CPC International).[0053]
Detergents
• The lipolytic enzyme produced by the invention may be used as a detergent additive, e.g. at a concentration (expressed as pure enzyme protein) of 0.001-10 (e.g. 0.01-1) mg per gram of detergent or 0.001-100 (e.g. 0.01-10) mg per liter of wash liquor.[0054]
• The detergent composition of the invention may for example be formulated as a hand or machine laundry detergent composition including a laundry additive composition suitable for pre-treatment of stained fabrics and a rinse added fabric softener composition, or be formulated as a detergent composition for use in general household hard surface cleaning operations. In a laundry detergent, the variant may be effective for the removal of fatty stains, for whiteness maintenance and for dingy cleanup. A laundry detergent composition may be formulated as described in WO 97/04079, WO 97/07202, WO 97/41212, PCT/DK WO 98/08939 and WO 97/43375.[0055]
• The detergent composition of the invention may particularly be formulated for hand or machine dishwashing operations. e.g. as described in GB 2,247,025 (Unilever) or WO 99/01531 (Procter & Gamble). In a dishwashing composition, the variant may be effective for removal of greasy/oily stains, for prevention of the staining/discoloration of the dishware and plastic components of the dishwasher by highly colored components and the avoidance of lime soap deposits on the dishware.[0056]
• The detergent composition of the invention may be in any convenient form, e.g., a bar, a tablet, a powder, a granule, a paste or a liquid. A liquid detergent may be aqueous, typically containing up to 70% water and 0-30% organic solvent, or non-aqueous.[0057]
• The detergent composition comprises one or more surfactants, which may be non-ionic including semi-polar and/or anionic and/or cationic and/or zwitterionic. The surfactants are typically present at a level of from 0.1% to 60% by weight, e.g. 0.5-40%, such as 1-30%, typically 1.5-20%.[0058]
Dough and Baked Products
• The lipolytic enzyme can be used in the preparation of dough and baked products made from dough, such as bread and cakes, e.g. to increase dough stability and dough handling properties, or to improve the elasticity of the bread or cake. Thus, it can be used in a process for making bread, comprising adding it to the ingredients of a dough, kneading the dough and baking the dough to make the bread. This can be done in analogy with U.S. Pat. No. 4,567,046 (Kyowa Hakko), JP-A 60-78529 (QP Corp.), JP-A 62-111629 (QP Corp.), JP-A 63-258528 (QP Corp.) or EP 426211 (Unilever). The lipolytic enzyme may be used together with an anti-staling amylase, particularly an endo-amylase such as a maltogenic amylase in analogy with WO 99/53769 (Novo Nordisk). Thus, the lipolytic enzyme may be incorporated in a flour composition such as a dough or a premix for dough.[0059]
MATERIALS AND METHODSStrains and PlasmidsPlasmid pMT2188
• The[0060]Aspergillus oryzaeexpression plasmid pCaHj 483 (WO 98/00529) consists of an expression cassette based on theAspergillus nigerneutral amylase II promoter fused to theAspergillus nidulanstriose phosphate isomerase non translated leader sequence (Pna2/tpi) and theA. nigeramyloglycosidase terminator (Tamg). Also present on the plasmid is the Aspergillus selective marker amdS fromA. nidulansenabling growth on acetamide as sole nitrogen source. These elements are cloned into theE. colivector pUC19 (New England Biolabs). The ampicillin resistance marker enabling selection inE. coliof this plasmid was replaced with the URA3 marker ofSaccharomyces cerevisiaethat can complement a pyrF mutation inE. coli, the replacement was done in the following way:
• The pUC19 origin of replication was PCR amplified from pCaHj483 with the primers 142779 (SEQ ID NO: 35) and 142780 (SEQ ID NO: 36).[0061]
• Primer 142780 introduces a Bbul site in the PCR fragment. The Expand PCR system (Roche Molecular Biochemicals, Basel, Switserland) was used for the amplification following the manufacturers instructions for this and the subsequent PCR amplifications.[0062]
• The URA3 gene was amplified from the general[0063]S. cerevisiaecloning vector pYES2 (Invitrogen corporation, Carlsbad, Calif., USA) using the primers 140288 (SEQ ID NO: 37) and 142778 (SEQ ID NO: 38).
• Primer 140288 introduces an EcoRI site in the PCR fragment. The two PCR fragments were fused by mixing them and amplifying using the primers 142780 and 140288 in the splicing by overlap method (Horton et al (1989) Gene, 77, 61-68).[0064]
• The resulting fragment was digested with EcoRI and BbuI and ligated to the largest fragment of pCaHj 483 digested with the same enzymes. The ligation mixture was used to transform the pyrF[0065]E. colistrain DB6507 (ATCC 35673) made competent by the method of Mandel and Higa (Mandel, M. and A. Higa (1970) J. Mol. Biol. 45, 154). Transformants were selected on solid M9 medium (Sambrook et. al (1989) Molecular cloning, a laboratory manual, 2. edition, Cold Spring Harbor Laboratory Press) supplemented with 1 g/l casaminoacids, 500 μg/l thiamine and 10 mg/l kanamycin.
• A plasmid from a selected transformant was termed pCaHj 527. The Pna2/tpi promoter present on pCaHj527 was subjected to site directed mutagenises by a simple PCR approach.[0066]
• Nucleotide 134-144 was altered from SEQ ID NO: 39 to SEQ ID NO: 40 using the mutagenic primer 141223 (SEQ ID NO: 41).[0067]
• Nucleotide 423-436 was altered from SEQ ID NO: 42 to SEQ ID NO: 43 using the mutagenic primer 141222 (SEQ ID 44).[0068]
• The resulting plasmid was termed pMT2188.[0069]
Plasmid pENI11861
• Plasmid pENI1861 was made in order to have the state of the art Aspergillus promoter in the expression plasmid, as well as a number of unique restriction sites for cloning.[0070]
• A PCR fragment (app. 620 bp) was made using pMT2188 (see above) as template and the primers 051199J1 (SEQ ID 45) and 1298TAKA (SEQ ID 46).[0071]
• The fragment was cut BssHII and Bgl II, and cloned into pENI11849 which was also cut with BssHII and Bgl II. The cloning was verified by sequencing. Plasmid pENI1902 was made in order to have a promoter that works in both[0072]E. coliand Aspergillus. This was done by unique site elimination using the “Chameleon double stranded site-directed mutagenesis kit” as recommended by Stratagene®.
Plasmid pENI1861
• Plasmid pENI1861 was used as template and the following primers with 5′ phosphorylation were used as selection primers: 177996 (SEQ ID 47), 135640 (SEQ ID 48) and 135638 (SEQ ID 49).[0073]
• The 080399J19 primer (SEQ ID NO: 50) with 5′ phosphorylation was used as mutagenic primer to introduce a −35 and −10 promoter consensus sequence (from[0074]E. coli) in the Aspergillus expression promoter. Introduction of the mutations was verified by sequencing.
Plasmid pENI1960
• Plasmid pENI1960 was made using the Gateway Vector™ conversion system (Lifetechnology® cat no. 11828-019) by cutting pENI1902 with BamHI, filling the DNA ends using Klenow fragment polymerase and nucleotides (thus making blunt ends) followed by ligation to reading frame A Gateway™ PCR fragment. The cloning in the correct orientation was confirmed by sequencing.[0075]
Media and Substrates

• Strains of[0077]Thermomyces ibadanensis, Talaromyces emersonii, Talaromyces byssochlamydoides, andTalaromyces thermophiluswere used as a genomic DNA supplier. Each strain was cultivated in 100 ml of YPG at appropriate temperature for several days. Mycelia was harvested and ground in liquid N₂. It was suspended with 2 ml of 50 mM Tris-HCl (pH8.0) buffer including 100 mM NaCl, 25 mM EDTA, and 1% SDS and then 12 μl of proteinase K (25 mg/ml) was added. The suspension was incubated at 65° C. for 30-60min. Phenol extraction was done to remove proteins and DNA was precipitated by 0.7 volume of isopropanol. The precipitate was dissolved with sterilized water and RNase was added. After Phenol/isoamylalcohol extraction, DNA was precipitated by EtOH.
PCR Screening of Lipolytic Enzyme Genes
• PCR reactions on each genomic DNA was done with HL 2 and HL12 (SEQ ID NO: 51 and 52) or HL2 and HL6 (SEQ ID NO: 51 and 53) designed based upon alignment lipases.[0078]
• Reaction components (2.6 ng /μl of genomic DNA, 250 mM dNTP each, primer 250 nM each, 0.1 U/μl of Taq polymerase in 1× buffer (Roche Diagnostics, Japan)) were mixed and submitted for PCR under the following conditions.[0079]

  	Step	Temperature	Time
  	1	94° C.	1 min
  	3	50° C.	1 min
  	4	72° C.	2 min
  	5	72° C.	10 min
  	6	4° C.	forever

• Steps 1 to 3 were repeated 30 times.[0080]
• 540 bp of fragment and 380 bp of fragment were amplified from primer sets of HL2/HL12 and HL2/HL6, respectively. They were gel-purified with GFX™ PCR DNA and Gel Band Purification kit (amersham pharmacia biotech) Each DNA was sequenced and compared to the lipase, showing that a clone encodes the internal part of the lipase.[0081]
Cloning of Lipase Genes
• All lipase genes were cloned using LA PCR™ in vitro Cloning Kit (TaKaRa) according to the manufacturer's instructions. Thus, genomic DNA was cut with various restriction enzymes and each DNA was ligated with the appropriate cassette of the kit. Each ligation solution was applied to PCR with the primers of the one designed from internal sequence and a cassette primer of the kit. Amplified DAN fragment was sequenced. This step was repeated till ORF was determined.[0082]
• The fidelity of LA-taq polymerase of the kit is not good so in order to get the right sequence whole gene was amplified by Expand high fidelity polymerase according to the manufacturer's instructions.[0083]
• Amplified DNA fragment was gel-purified with GFX™ PCR DNA and Gel Band Purification kit (Amersham Pharmacia Biotech) and ligated into a pT7Blue vector or pST BLue-1 AccepTor vector (Novagen) with ligation high (TOYOBO, Japan). The ligation mixtures were transformed into[0084]E. coliJM109 or DH5α. The sequence of four plasmids of each gene was determined and their sequence were compared. The sequence of majority is defined as the right nucleotide sequence.

Example 4Shuffling of Lipolytic Enzyme Genes
• Plasmids containing DNA sequences encoding lipolytic enzymes are mixed in equimolar amounts. The following components where mixed in a microtube:[0115]
• 2 μl plasmid mixture (0.15 μg/μl), specific primers flanking the gene (1 pmol/μ), 2 μl 2.5 mM dNTP, 2.5 mM MgCl2, 2 μl 10* taq buffer (Perkin Elmer), 0.5 μl taq enzyme in a total volume of 20 μl.[0116]
• The tube is set in a Perkin Elmer 2400 thermocycler. The following PCR-program is run:(94° C., 5 minutes) 1 cycle:[0117]
• (94° C., 30 seconds, 70° C., 0 seconds) 99 cycles(72° C., 2 minutes, 4° C. indefinite) 1 cycle.[0118]
• The PCR-reaction is run on a 1.5% agarose gel. A DNA-band of the specific expected size is cut out of the agarose gel and purified using JETsorb (from GENOMED Inc.). The purified PCR-product is cloned into a TA-vector (from Invitrogen (the original TA cloning kit). The ligated product is transformed into a standard Escherichia coli strain (DH5a).[0119]
• The shuffled sequences can then be subcloned from the[0120]E. coliTA vector into the yeast vector pJSOO26 (WO 9928448) as a BamHI-Xbal fragment (see WO 97/07205), and e.g. screened for new shuffled sequences with improved properties, e.g. improved performance in detergents (see WO 97/07205).
Example 5Shuffling of Lipolytic Enzyme Genes
• PCR products of lipolytic enzyme genes are generated as in the previous example and pooled in equimolar amounts. The following mixture is generated in a suitable tube:[0121]
• 1 μl PCR mixture (0.1 μg), decamer random primer (300 pmol), 2 μl 10* Klenow buffer (Promega), 0.25 mM dNTP, 2.5 mM MgCl2 in a total volume of 20 μl.[0122]
• The mixture is set in a PE2400 thermocycler where the following program is run: 96° C., 5 minutes, 25° C. 5 minutes, 0.5 ml Klenow enzyme is added, 25° C. 60 minutes, 35° C. 90 minutes.[0123]
• This procedure generates a high number of small DNA polymers originating from all parts of the gene.[0124]
• 10 μl is taken out for test on agarose gel.[0125]
• 10 μl PCR mixture (0.25 mM dNTP, 1 μl 10* Taq buffer (Perkin Elmer), 2.5 mM MgCl2, 0.5 μl Taq enzyme) is added to the 10 μl in the tube in the thermocycler.

• The PCR-product and the desired vector are cut with the appropriate restriction enzymes (BamHI/XhoI). The vector and the PCR product are run on a 1.5% agarose gel, and purified from the gel.[0130]
• The cut PCR-product and the cut vector are mixed in a ligase buffer with T4 DNA ligase (Promega). After overnight ligation at 16° C. the mixture is transformed into[0131]E. colistrain DH5a.
Example 6Creation of Intron-Less Lipase Genes
• A number of lipase genes with homology to the[0132]Thermomyces lanuginosuslipase gene were cloned. These genes were cloned as genomic DNA and were thus known to contain introns.
• The intention was to shuffle these genes in order to obtain chimeric genes. In order to obtain the highest possible quality of library, the introns had to be removed. This was done by creating DNA oligo's matching each flank of an exon as well as having a DNA sequence, which is homologous to the next neighbour exon.[0133]
• These oligoes were used in standard PCR (as known to a person skilled in the art), thus creating PCR fragments covering each and every exon (coding sequence) in the gene. These PCR fragments were purified from a 1% agarose gel. The PCR fragments were assembled into a full length gene, in a second PCR using the DNA oligoes flanking the whole gene, as primers.[0134]
• The PCR fragment-containing the full length intron-less gene encoding the lipase was cloned into pENI 1960 as described in pat. appl. PCT/DK02/00050.[0135]
• The following primers were used to assemble each intron-less gene:[0136]
• [0137]Talaromyces thermophilus:051200j1, 051200J2, 051200J3, 051200J4, 051200J5, 051200J6, 051200J7 and 051200J8 (SEQ ID NO: 11-18), thus creating pENI2178, when cloned into pENI1960.
• [0138]Talaromyces emersonii:051200J9, 051200J10, 051200J11, 051200J12, 051200J13, 051200J14, 051200J15 and 051200J16 (SEQ ID NO: 19-26), thus creating pENI2159, when cloned into pENI1960.
• [0139]Thermomyces ibadanensis:051200J17, 051200J18, 051200J19, 051200J20, 051200J21, 051200J22, 051200J23 and 051200J24 (SEQ ID NO: 27-34), thus creating pENI2160, when cloned into pENI1960.
• [0140]Talaromyces byssochlamydoides:080201P1, 080201P2, 080201P3, 080201P4, 080201 P5, 080201P6, 080201P7 and 080201P8 (SEQ ID NO: 54-61), thus creating pENI2230 when cloned into pENI1960.
Example 7Shuffling of the Intron-Less Lipase Genes
• A method using dUTP and uracil-DNA glycosylase was employed in order to make DNA fragments in sufficient quantities for DNA shuffling. The 3 genes[0141]T. lanuginosus, T. thermophilusandT. ibadanensisare quite homologous to each other (thus named Group A) as areT. emersoniiandT. byssochlamydoides(named Group B). Thus in order to improve recombination between the two groups the following PCR scheme (see FIG. 1) was employed, using the following templates: pENI2178, pENI2159, pENI2160, pENI2230, and theT. lanuginosusgene cloned into pENI1902 (cut BamHI and SacII) (pat. PCT/DK02/00050).
• The following oligonucleotides are shown in FIG. 1: 1298-taka, 19670, 19672, 115120 and 050401P6 (SEQ ID NO: 62-65 and 68). 050401P1 (SEQ ID NO: 66) hybridises to 5[0142]′ T. lanuginoselipase gene. 030501 P1 (SEQ ID NO: 67) hybridises to 5′ of the other 4 lipase genes.
• The final PCR fragment was cut first with BstEII and then with Sfil, as was the vector pENI2376. pENI2376 is a derivative of pENI1861(pat. PCT/DK02/00050).[0143]
• The vector and PCR-fragment was purified from a 1% gel and ligated O/N. The ligated DNA pool was transformed into electro-competent[0144]E. coliDH10B, thus creating a library of app. 700.000 independent clones.
• This library can be screened for activity towards various substrates such as Lecithin, DGDG, triglycerides such as tributyrine, olive oil, PNP-valerate or PNP-palmitate at different conditions such as high pH, low pH, high temperature, in presences of detergent, in the presence of ions or in the absence of ions.[0145]
• This can be done in order to find, e.g., a thermo-stable lipase, a detergent phospholipase, a detergent lipase with first-wash performance, and no activity at neutral pH and so forth.[0146]

Example 8Characterization of Lipolytic Enzymes
• Lipolytic enzymes from[0147]Thermomyces ibadanensisandTalaromyces thermophiluswere prepared as described above, purified and used for characterization
• The specific lipase activity was determined by the LU method described in WO 0032758, and the amount of enzyme protein was determined from the optical density at 280 nm. The specific activity was found to be 3181 LU/mg for the[0148]Th. ibadanensislipase and 1000 LU/mg for theTal. thermophiluslipase.
• The pH-activity relation was found by determining the lipase by the LU method at pH 5, 6, 7, 8, 9 and 10. Both enzymes were found to have the highest lipase activity at pH 10. The[0149]Th. ibadanensislipase showed a broad optimum with more than 50% of maximum activity in the pH range 6-10 whereas theTal. thermophiluslipase showed a stronger activity drop at lower pH with less than 30% of maximum activity at pH 5-8.
• The thermostability was determined by differential scanning calorimetry (DSC) at pH 5 (50 mM acetate buffer), pH 7 (50 mM HEPES buffer) and pH 10 (50 mM glycine buffer) with a scan rate of 90° C./hr. The temperature at the top of the denaturation peak (T[0150]_d) was found to be as follows:

  	Td(° C.)

• The results were that the enzyme from[0152]T. ibadanensisshowed high lysophospholipase activity at pH 5 and some activity at pH 7. The enzyme fromT. thermosshowed a slight activity.
