Nitrate reductase (NADPH)
Ec Number:	1.7.1.3
Cas Number:	9029-28-1

Nitrate reductase (NADPH) (assimilatory nitrate reductase, assimilatory reduced nicotinamide adenine dinucleotide phosphate-nitrate reductase, NADPH-nitrate reductase, assimilatory NADPH-nitrate reductase, triphosphopyridine nucleotide-nitrate reductase, NADPH:nitrate reductase, nitrate reductase (NADPH₂), NADPH₂:nitrate oxidoreductase) is an enzyme with systematic name nitrite:NADP⁺ oxidoreductase.^{[1] [2] [3] [4]} This enzyme catalises the following chemical reaction

nitrite + NADP⁺ + H₂O

\rightleftharpoons nitrate + NADPH + H⁺

Nitrate reductase is an iron-sulfur molybdenum flavoprotein.
