Entry
Name
arsenate-mycothiol transferase;
ArsC1;
ArsC2;
mycothiol:arsenate transferase
Class
Transferases;
Transferring sulfur-containing groups;
Transferring alkylthio groups
BRITE hierarchy
Sysname
mycothiol:arsenate S-arsenotransferase
Reaction(IUBMB)
arsenate + mycothiol = arseno-mycothiol + H2O
Substrate
Product
arseno-mycothiol;
H2O [CPD:
C00001 ]
Comment
Reduction of arsenate is part of a defence 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.
