Ferredoxin—NADP(+) Reductase
In enzymology, a ferredoxin-NADP reductase () abbreviated FNR, 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. It has a flavin cofactor, FAD. This enzyme belongs to the family of oxidoreductases, that use iron-sulfur proteins as electron donors and NAD or NADP as electron acceptors. This enzyme participates in photosynthesis. FNR provides a major source of NADPH for photosynthetic organisms. Nomenclature The systematic name of this enzyme class is ferredoxin:NADP oxidoreductase. Other names in common use include: * adrenodoxin reductase, * ferredoxin-NADP reductase, * ferredoxin-NADP oxidoreductase, * ferredoxin-nicotinamide adenine dinucleotide phosphate reductase, * ferredoxin-nicotinamide-adenine dinucleotide phosphate (oxidized), reductase * ferredoxin-TP ...

Ferredoxin—NAD(+) Reductase
In enzymology, a ferredoxin–NAD+ reductase () is an enzyme that catalyzes the chemical reaction: :reduced ferredoxin + NAD+ \rightleftharpoons oxidized ferredoxin + NADH + H+ Thus, the two substrates of this enzyme are reduced ferredoxin and NAD+, whereas its 3 products are oxidized ferredoxin, NADH, and H+. This enzyme participates in fatty acid metabolism. 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 is ferredoxin:NAD+ oxidoreductase. There are a variety of names in common use: *ferredoxin–nicotinamide adenine dinucleotide reductase *ferredoxin reductase *NAD+-ferredoxin reductase *ferredoxin–NAD+ reductase *ferredoxin–linked NAD+ reductase *ferredoxin–NAD reductase When NAD molecule is in its reduced form, the enzyme is referred to as: *NADH-ferredoxin oxidoreductase *reduced nicotinamide adenine dinucleotide-ferredoxin *NADH ...

Ferredoxin—nitrite Reductase
In enzymology, a ferredoxin—nitrite reductase () is an enzyme that catalyzes the chemical reaction :NH3 + 2 H2O + 6 oxidized ferredoxin \rightleftharpoons nitrite + 6 reduced ferredoxin + 7 H+ The 3 substrates of this enzyme are NH3, H2O, and oxidized ferredoxin, whereas its 3 products are nitrite, reduced ferredoxin, and H+. This enzyme belongs to the family of oxidoreductases, specifically those acting on other nitrogenous compounds as donors with an iron-sulfur protein as acceptor. The systematic name of this enzyme class is ammonia:ferredoxin oxidoreductase. This enzyme participates in nitrogen metabolism and nitrogen assimilation. It has 3 cofactors: iron, Siroheme, and Iron-sulfur. This enzyme can use many different isoforms of ferredoxin. In photosynthesizing tissues, it uses ferredoxin that is reduced by PSI and in the root it uses a form of ferredoxin (FdIII) that has a less negative midpoint potential and can be reduced easily by NADPH.
