ID   1.7.1.4
DE   nitrite reductase [NAD(P)H].
AN   assimilatory nitrite reductase.
AN   NAD(P)H:nitrite oxidoreductase.
AN   NADH-nitrite oxidoreductase.
AN   NADPH-nitrite reductase.
AN   nitrite reductase (reduced nicotinamide adenine dinucleotide
AN   (phosphate)).
CA   (1) 2 H2O + 3 NAD(+) + NH4(+) = 5 H(+) + 3 NADH + nitrite.
CA   (2) 2 H2O + 3 NADP(+) + NH4(+) = 5 H(+) + 3 NADPH + nitrite.
CC   -!- The enzymes from the fungi Neurospora crassa, Emericella nidulans and
CC       Candida nitratophila can use either NADPH or NADH as electron donor.
CC       cf. EC 1.7.1.15.
CC   -!- Formerly EC 1.6.6.4.
