IntEnz Enzyme Nomenclature
EC 1.7.1.4

Names

Accepted name:
nitrite reductase [NAD(P)H]
Other names:
NAD(P)H2:nitrite oxidoreductase
NADH-nitrite oxidoreductase
NADPH-nitrite reductase
assimilatory nitrite reductase [ambiguous]
nitrite reductase (reduced nicotinamide adenine dinucleotide (phosphate))
nitrite reductase [NAD(P)H2]
NAD(P)H:nitrite oxidoreductase
nit-6 (gene name)
Systematic name:
ammonia:NAD(P)+ oxidoreductase

Reaction

Cofactors

Comments:

An iron-sulfur flavoprotein (FAD) containing siroheme. The enzymes from the fungi Neurospora crassa [1], Emericella nidulans [2] and Candida nitratophila [4] can use either NADPH or NADH as electron donor. cf. EC 1.7.1.15, nitrite reductase (NADH).
