Hydroxylamine dehydrogenase (, HAO (ambiguous)) is an enzyme with systematic name hydroxylamine:ferricytochrome-c oxidoreductase. This enzyme catalyses the following chemical reaction
(1) hydroxylamine + H2O + 2 ferricytochrome c nitrite + 2 ferrocytochrome c + 5 H+ (2) hydroxylamine + ferricytochrome c nitric oxide + ferrocytochrome c + 3 H+
The enzymes from the nitrifying bacterium Nitrosomonas europaea and the methylotrophic bacterium Methylococcus capsulatus are hemoproteins.
