ENZYME entry: EC2.8.1.2

PURL:https://purl.expasy.org/enzyme/EC/2.8.1.2
Accepted Name
3-mercaptopyruvate sulfurtransferase
Reaction catalysed
2-oxo-3-sulfanylpropanoate +[thioredoxin]-dithiol =[thioredoxin]-disulfide +hydrogen sulfide +pyruvate +H(+)
Comment(s)
  • The enzyme catalyzes a transsulfuration reaction from 3-mercaptopyruvate to an internal cysteine residue.
  • In the presence of a dithiol such as reduced thioredoxin or dihydrolipoate, the sulfanyl sulfur is released as hydrogen sulfide.
  • The enzyme participates in a sulfur relay process that leads to the 2-thiolation of some tRNAs and to protein urmylation by transferring sulfur between the NFS1 cysteine desulfurase (EC2.8.1.7) and the MOCS3 sulfurtransferase (EC2.8.1.11).
