FunFam 2: Hydroxylamine oxidoreductase

Please note: GO 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.

There are 4 GO terms relating to "molecular function"

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.
GO Term Annotations Evidence
Oxidoreductase activity GO:0016491
Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced.
4 Q50925 (/IDA) Q50925 (/IDA) Q50925 (/IDA) Q50925 (/IDA)
Hydroxylamine oxidase activity GO:0047991
Catalysis of the reaction: hydroxylamine + O(2) = H(2)O + H(+) + nitrite.
4 Q50925 (/IDA) Q50925 (/IDA) Q50925 (/IDA) Q50925 (/IDA)
Oxidoreductase activity, acting on other nitrogenous compounds as donors, oxygen as acceptor GO:0016663
Catalysis of an oxidation-reduction (redox) reaction in which a nitrogenous group, excluding NH and NH2 groups, acts as a hydrogen or electron donor and reduces oxygen.
1 Q60AB1 (/ISS)
Hydroxylamine oxidase activity GO:0047991
Catalysis of the reaction: hydroxylamine + O(2) = H(2)O + H(+) + nitrite.
1 Q5LL28 (/ISS)

There are 3 GO terms relating to "biological process"

GO Term Annotations Evidence
Anaerobic respiration, using ammonium as electron donor GO:0019331
The oxidation of ammonium (NH4) to nitrogen (N2) in the absence of oxygen, using nitrite (NO2) as the electron acceptor. It is suggested that hydroxylamine and ammonium are combined to yield hydrazine, which is subsequently oxidized to N2.
4 Q50925 (/IDA) Q50925 (/IDA) Q50925 (/IDA) Q50925 (/IDA)
Ammonia oxidation GO:0019329
The chemical reactions and pathways by which ammonia or ammonium is converted to molecular nitrogen or another nitrogen compound, with accompanying loss of electrons.
1 Q5LL28 (/ISS)
Oxidation-reduction process GO:0055114
A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.
1 Q60AB1 (/ISS)
