IntEnz Enzyme Nomenclature
EC 1.7.1.15

Names

Accepted name:
nitrite reductase (NADH)
Other names:
nitrite reductase (reduced nicotinamide adenine dinucleotide)
NADH-nitrite oxidoreductase
assimilatory nitrite reductase [ambiguous]
nirB (gene name)
nirD (gene name)
Systematic name:
ammonia:NAD+ oxidoreductase

Reaction

Cofactors

Comments:

An iron-sulfur flavoprotein (FAD) containing siroheme. This prokaryotic enzyme is specific for NADH. In addition to catalysing the 6-electron reduction of nitrite to ammonia, the enzyme from Escherichia coli can also catalyse the 2-electron reduction of hydroxylamine to ammonia. cf. EC 1.7.1.4, nitrite reductase [NAD(P)H].
