Glucan 1,4-α-glucosidase (EC3.2.1.3,glucoamylase, amyloglucosidase, γ-amylase, lysosomal α-glucosidase, acid maltase, exo-1,4-α-glucosidase, glucose amylase, γ-1,4-glucan glucohydrolase, acid maltase, 1,4-α-D-glucan glucohydrolase) is anenzyme located on the brush border of the small intestine withsystematic name4-α-D-glucan glucohydrolase.[1][2][3][4][5][6] Itcatalyses the followingchemical reaction
Most forms of the enzyme can rapidly hydrolyse 1,6-α-D-glucosidic bonds when the next bond in the sequence is 1,4. They belong to a variety of different families, such asglycoside hydrolase family 15 in fungi,glycoside hydrolase family 31 of human intestineMGAM, andglycoside hydrolase family 97 of bacterial forms. It was also known as γ-amylase.
