FunFam 2: Hydroxylamine oxidoreductase

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Hydroxylamine dehydrogenase. [EC: 1.7.2.6]
(1) Hydroxylamine + H(2)O + 4 ferricytochrome c = nitrite + 4 ferrocytochrome c + 5 H(+). (2) Hydroxylamine + 3 ferricytochrome c = nitric oxide + 3 ferrocytochrome c + 3 H(+).
  • 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.
