Arsenate reductase (glutaredoxin)

In enzymology, an arsenate reductase (glutaredoxin) is an enzyme that catalyzes the chemical reaction


 * arsenate + glutaredoxin $$\rightleftharpoons$$ arsenite + glutaredoxin disulfide + H2O

Thus, the two substrates of this enzyme are arsenate and glutaredoxin, whereas its 3 products are arsenite, glutaredoxin disulfide, and H2O.

This enzyme belongs to the family of oxidoreductases, specifically those acting on phosphorus or arsenic in donor with disulfide as acceptor. The systematic name of this enzyme class is glutharedoxin:arsenate oxidoreductase.
