Superfamily Cytochrome P450
Functional Family Cytochrome P450 monooxygenase

Enzyme Information

1.7.1.14
Nitric oxide reductase (NAD(P)(+), nitrous oxide-forming).
based on mapping to UniProt P23295
Nitrous oxide + NAD(P)(+) + H(2)O = 2 nitric oxide + NAD(P)H.
-!- 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.
