ID   1.7.1.14
DE   nitric oxide reductase [NAD(P)(+), nitrous oxide-forming].
AN   cytochrome P450nor.
AN   fungal nitric oxide reductase.
AN   NOR.
CA   (1) nitrous oxide + NAD(+) + H2O = 2 nitric oxide + NADH + H(+).
CA   (2) nitrous oxide + NADP(+) + H2O = 2 nitric oxide + NADPH + H(+).
CC   -!- The enzyme from Fusarium oxysporum utilizes only NADH, but the
CC       isozyme from Trichosporon cutaneum utilizes both NADH and NADPH.
CC   -!- The electron transfer from NAD(P)H to heme occurs directly,
CC       not requiring flavin or other redox cofactors.
