Azurin

Arsenate reductase (azurin)

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

arsenite + H2O + 2 azurinox rightleftharpoons arsenate + 2 azurinred + 2 H+

The 3 substrates of this enzyme are arsenite, H2O, and azurinox, whereas its 3 products are arsenate, azurinred, and H+.

This enzyme belongs to the family of oxidoreductases, specifically those acting on phosphorus or arsenic in donor with other, known, acceptors. The systematic name of this enzyme class is arsenite:azurin oxidoreductase. This enzyme is also called arsenite oxidase.
