Mycoredoxin

Mycoredoxin (, Mrx1, MrxI) is an enzyme with systematic name arseno-mycothiol:mycoredoxin oxidoreductase. This enzyme catalyses the following chemical reaction


 * arseno-mycothiol + mycoredoxin $$\rightleftharpoons$$ arsenite + mycothiol-mycoredoxin disulfide

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