Arsenate reductase (azurin) ( EC 1.20.9.1) is an enzyme that catalyzes the chemical reaction
The 3 substrates of this enzyme are arsenite, water, and oxidised azurin, whereas its 3 products are arsenate, reduced azurin, and hydrogen ion.
This enzyme belongs to the family of oxidoreductases, specifically those acting on phosphorus or arsenic in donor with a copper protein as acceptor.
The systematic name of this enzyme class is arsenite:azurin oxidoreductase. This enzyme is also called arsenite oxidase.
The enzyme contains a molybdopterin centre comprising two
molybdopterin
guanosine dinucleotide cofactors bound to
molybdenum, a
[3Fe-4S] cluster and a
Rieske-type [2Fe-2S] cluster. Also uses a c-type
cytochrome or
O
2 as acceptors.
