ENZYME entry: EC 1.7.1.14

Accepted Name
nitric oxide reductase [NAD(P)(+), nitrous oxide-forming]
Alternative Name(s)
cytochrome P450nor
fungal nitric oxide reductase
NOR
Reaction catalysed
  • H2O + NAD(+) + nitrous oxide <=> H(+) + NADH + 2 nitric oxide
  • H2O + NADP(+) + nitrous oxide <=> H(+) + NADPH + 2 nitric oxide
Comment(s)
  • The enzyme from Fusarium oxysporum utilizes only NADH, but the isozyme from Trichosporon cutaneum utilizes both NADH and NADPH.
  • The electron transfer from NAD(P)H to heme occurs directly, not requiring flavin or other redox cofactors.
