From Wikipedia, the free encyclopedia

Hydroxylamine dehydrogenase (EC 1.7.2.6, HAO (ambiguous)) is an enzyme with systematic name hydroxylamine:ferricytochrome-c oxidoreductase.[1][2][3][4][5] This enzyme catalyses the following chemical reaction

(1) hydroxylamine + H2O + 2 ferricytochrome c
(2) hydroxylamine + ferricytochrome c

The enzymes from the nitrifying bacterium Nitrosomonas europaea and the methylotrophic bacterium Methylococcus capsulatus are hemoproteins.
