FunFam 71673: Arsenate-mycothiol transferase ArsC1

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
Arsenate-mycothiol transferase. [EC: 2.8.4.2]
Arsenate + mycothiol = arseno-mycothiol + H(2)O.
  • Reduction of arsenate is part of a defense mechanism of the cell against toxic arsenate.
  • The product arseno-mycothiol is reduced by EC 1.20.4.3 (mycoredoxin) to arsenite and mycothiol-mycoredoxin disulfide.
  • Finally, a second mycothiol recycles mycoredoxin and forms mycothione.
