ENZYME entry: EC

Accepted Name
hydroxylamine oxidase (cytochrome).
Alternative Name(s)
hydroxylamine oxidase.
hydroxylamine oxidoreductase.
Reaction catalysed
hydroxylamine + O2 <=> H(+) + H2O + nitrite
  • The enzyme from the heterotrophic nitrifying bacterium Paracoccus denitrificans contains three to five non-heme, non-iron-sulfur iron atoms and interacts with cytochrome c556 and pseudoazurin.
  • Under anaerobic conditions in vitro only nitrous oxide is formed.
  • Presumably nitroxyl is released and combines with a second nitroxyl to give nitrous oxide and water.
  • When oxygen is present, nitrite is formed.
  • Formerly EC
