ENZYME entry: EC 1.7.2.6
Accepted Name |
hydroxylamine dehydrogenase.
|
Alternative Name(s) |
hydroxylamine oxidase. |
hydroxylamine oxidoreductase. |
Reaction catalysed |
4 Fe(III)-[cytochrome c] + H2O + hydroxylamine <=> 4 Fe(II)-[cytochrome c] + 5 H(+) + nitrite |
Comment(s) |
- The enzymes from the nitrifying bacterium Nitrosomonas europaea and
the methylotrophic bacterium Methylococcus capsulatus are
hemoproteins with seven c-type hemes and one specialized P460-type
heme per subunit.
- The enzyme converts hydroxylamine to nitrite via an enzyme-bound
nitroxyl intermediate.
- While nitrite is the main product, the enzyme from Nitrosomonas
europaea can also produce nitric oxide by catalyzing the activity of
EC 1.7.2.9.
- Formerly EC 1.7.3.4.
