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.
