Arsenat reduktaza (citohrom c) (EC 1.20.2.1, arsenitna oksidaza) je enzim sa sistematskim imenom arsenit:citohrom c oksidoreduktaza.[1][2][3][4] Ovaj enzim katalizuje sledeću hemijsku reakciju:

arsenit + H2O + 2 oksidovani citohrom c arsenat + 2 redukovani citohrom c + 2 H+

Ovaj molibdoprotein sadrži gvožđe-sumporne klastere. On je izolovan iz alfa-proteobakterija.
