Arsenate reductase (azurin) (EC 1.20.98.1) is an enzyme that catalyzes the chemical reaction
- arsenite + H2O + 2 azurinox
arsenate + 2 azurinred + 2 H+
arsenate + 2 azurinred + 2 H+The 3 substrates of this enzyme are arsenite, water, and azurinox, whereas its 3 products are arsenate, azurinred, and hydrogen ion.
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.
