Hidroksilamin dehidrogenaza (EC 1.7.2.6, HAO (nespecifična), hidroksilamin oksidoreduktaza (nespecifična)) je enzim sa sistematskim imenom hidroksilamin:fericitohrom-c oksidoreduktaza.[1][2][3][4][5] Ovaj enzim katalizuje sledeću hemijsku reakciju
- (1) hidroksilamin + H2O + 2 fericitohrom c nitrit + 2 ferocitohrom c + 5 H+
- (2) hidroksilamin + fericitohrom c azot oksid + ferocitohrom c + 3 H+
Enzimi iz nitrifikujućih bakterija Nitrosomonas europaea i metilotrofnih bakterija Metilococcus capsulatus su hemoproteini sa sedam c-tip hemova i jednim specijalizovanim P-460-tipom hema po podjedinici.
