EC 1.18.1.2

Accepted name: ferredoxin—NADP+ reductase

Reaction: 2 reduced ferredoxin + NADP+ + H+ = 2 oxidized ferredoxin + NADPH

Other name(s): ferredoxin-nicotinamide adenine dinucleotide phosphate reductase; ferredoxin-NADP+ reductase; TPNH-ferredoxin reductase; ferredoxin-NADP+ oxidoreductase; NADP+:ferredoxin oxidoreductase; ferredoxin-TPN reductase; ferredoxin-NADP+-oxidoreductase; NADPH:ferredoxin oxidoreductase; ferredoxin-nicotinamide-adenine dinucleotide phosphate (oxidized) reductase

Systematic name: ferredoxin:NADP+ oxidoreductase

Comments: A flavoprotein (FAD). In chloroplasts and cyanobacteria the enzyme acts on plant-type [2Fe-2S] ferredoxins, but in other bacteria it can also reduce bacterial 2[4Fe-4S] ferredoxins and flavodoxin.
