In enzymology, a NADPH dehydrogenase (quinone) (EC 1.6.5.10) 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. The systematic name of this enzyme class is NADPH:(quinone-acceptor) oxidoreductase. Other names in common use include reduced nicotinamide adenine dinucleotide phosphate (quinone), dehydrogenase, NADPH oxidase, and NADPH2 dehydrogenase (quinone). It has 2 cofactors: FAD, and Flavoprotein. Several compounds are known to inhibit this enzyme, including Folate, and Dicumarol.
Structural studies
[edit]As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code 1F5V.
