Rubredoxin—NAD(+) reductase

Template:Short description Template:Infobox enzyme In enzymology, a rubredoxin-NAD⁺ reductase (Template:EC number) is an enzyme that catalyzes the chemical reaction.

2 reduced rubredoxin + NAD⁺ + H⁺ $\rightleftharpoons$ 2 oxidized rubredoxin + NADH

The 3 substrates of this enzyme are reduced rubredoxin, NAD⁺, and H⁺, whereas its two products are oxidized rubredoxin and NADH.

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 rubredoxin:NAD⁺ oxidoreductase. Other names in common use include rubredoxin reductase, rubredoxin-nicotinamide adenine dinucleotide reductase, dihydronicotinamide adenine dinucleotide-rubredoxin reductase, reduced nicotinamide adenine dinucleotide-rubredoxin reductase, NADH-rubredoxin reductase, rubredoxin-NAD reductase, NADH: rubredoxin oxidoreductase, DPNH-rubredoxin reductase, and NADH-rubredoxin oxidoreductase. This enzyme participates in fatty acid metabolism. It has 2 cofactors: FAD and Iron.

Structural studies
