The 3 substrates of this enzyme are reduced rubredoxin, NAD+, and NADP+, whereas its 4 products are oxidized rubredoxin, NADH, NADPH, and H+.[1][2]
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(P)+ oxidoreductase. Other names in common use include rubredoxin-nicotinamide adenine dinucleotide (phosphate) reductase, rubredoxin-nicotinamide adenine, dinucleotide phosphate reductase, NAD(P)+-rubredoxin oxidoreductase, and NAD(P)H-rubredoxin oxidoreductase. This enzyme participates in fatty acid metabolism.
