Ferredoxin-NADP+ reductase

In enzymology, a ferredoxin---NADP+ reductase is an enzyme that catalyzes the chemical reaction


 * 2 reduced ferredoxin + NADP+ + H+ $$\rightleftharpoons$$ 2 oxidized ferredoxin + NADPH

The 3 substrates of this enzyme are reduced ferredoxin, NADP+, and H+, whereas its two products are oxidized ferredoxin and NADPH.

This enzyme belongs to the family of oxidoreductases, specifically those acting on iron-sulfur proteins as donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is ferredoxin:NADP+ oxidoreductase. Other names in common use include adrenodoxin reductase, ferredoxin-nicotinamide adenine dinucleotide phosphate reductase, ferredoxin-NADP+ reductase, TPNH-ferredoxin reductase, ferredoxin-NADP+ oxidoreductase, NADP+:ferredoxin oxidoreductase, ferredoxin-TPN reductase, reduced nicotinamide adenine dinucleotide phosphate-adrenodoxin, reductase, ferredoxin-NADP+-oxidoreductase, NADPH:ferredoxin oxidoreductase, ferredoxin-nicotinamide-adenine dinucleotide phosphate (oxidized), reductase, and ferredoxin---NADP+ reductase. This enzyme participates in photosynthesis. It has 2 cofactors: FAD, and Flavin.
