FunFam 231: Probable 3-mercaptopyruvate sulfurtransferase

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
3-mercaptopyruvate sulfurtransferase. [EC: 2.8.1.2]
3-mercaptopyruvate + reduced thioredoxin = pyruvate + hydrogen sulfide + oxidized thioredoxin.
  • 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 (EC 2.8.1.7) and the MOCS3 sulfurtransferase (EC 2.8.1.11).
