ENZYME entry: EC 1.7.2.6
Accepted Name |
Hydroxylamine dehydrogenase.
|
Alternative Name(s) |
Hydroxylamine oxidase. |
Reaction catalysed |
- Hydroxylamine + H(2)O + 4 ferricytochrome c <=> nitrite + 4 ferrocytochrome c + 5 H(+)
- Hydroxylamine + 3 ferricytochrome c <=> nitric oxide + 3 ferrocytochrome c + 3 H(+)
|
Cofactor(s) |
Heme.
|
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 produce nitric oxide as well.
- Formerly EC 1.7.3.4.
