Arsenate reductase (cytochrome c) (EC 1.20.2.1, arsenite oxidase) is an enzyme with systematic name arsenite:cytochrome c oxidoreductase. [1] [2] [3] [4] This enzyme catalyses the following chemical reaction

arsenite + H2O + 2 oxidized cytochrome c arsenate + 2 reduced cytochrome c + 2 H+

Arsenate reductase is a molybdoprotein isolated from alpha-proteobacteria that contains iron-sulfur clusters.
