In enzymology, a NADPH dehydrogenase () is an enzyme that catalyzes the chemical reaction
NADPH + H+ + acceptor NADP+ + reduced acceptor
The 3 substrates of this enzyme are NADPH, H+, and acceptor, whereas its two products are NADP+ and reduced acceptor.
This enzyme belongs to the family of oxidoreductases, specifically those acting on NADH or NADPH with other acceptors. It has 2 cofactors: FAD, and FMN.
Nomenclature
The systematic name of this enzyme class is NADPH:acceptor oxidoreductase. Other names in common use include
NADPH2 diaphorase NADPH diaphorase old yellow enzyme diaphorase dihydronicotinamide adenine dinucleotide phosphate dehydrogenase NADPH-dehydrogenase NADPH-diaphorase NADPH2-dehydrogenase reduced nicotinamide adenine dinucleotide phosphate dehydrogenase TPNH dehydrogenase TPNH-diaphorase triphosphopyridine diaphorase triphosphopyridine nucleotide diaphorase NADPH2 dehydrogenase NADPH:(acceptor) oxidoreductase.
