Reaction: hydrazine + acceptor = N2 + reduced acceptor
Other name(s): HAO (ambiguous; cf. EC 1.7.3.4 hydroxylamine oxidase)
Systematic name: hydrazine:acceptor oxidoreductase
Comments: The enzyme is involved in the pathway of anaerobic ammonium oxidation in anammox bacteria. The conversion of hydroxylamine by the enzyme from Brocadia anammoxidans results in the formation of NO and N2O [1]. Hydroxylamine is not a substrate for the enzyme from planctomycete KSU-1 [2].
