EC 1.7.1.14 Details
EC number
1.7.1.14
Accepted name
nitric oxide reductase [NAD(P)+, nitrous oxide-forming]
Reaction
N2O + NAD(P)+ + H2O = 2 NO + NAD(P)H + H+
Other name(s)
fungal nitric oxide reductase, cytochrome P450nor, NOR (ambiguous)
Systematic name
nitrous oxide:NAD(P) oxidoreductase
Comment
A heme-thiolate protein (P-450). 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.
