Arsenate-mycothiol transferase

Arsenate-mycothiol transferase (, ArsC1, ArsC2, mycothiol:arsenate transferase) is an enzyme with systematic name mycothiol:arsenate S-arsenotransferase. This enzyme catalyses the following chemical reaction



mycothiol + arsenate $$\rightleftharpoons$$ arseno-mycothiol + H2O

Reduction of arsenate is part of a defence mechanism of the cell against toxic arsenate.
