In enzymology, a NADPH dehydrogenase (EC 1.6.99.1) is an enzyme that catalyzes the chemical reaction

Contents

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

A dehydrogenase is an enzyme belonging to the group of oxidoreductases that oxidizes a substrate by reducing an electron acceptor, usually NAD+/NADP+ or a flavin coenzyme such as FAD or FMN. Like all catalysts, they catalyze reverse as well as forward reactions, and in some cases this has physiological significance: for example, alcohol dehydrogenase catalyzes the oxidation of ethanol to acetaldehyde in animals, but in yeast it catalyzes the production of ethanol from acetaldehyde.

<span class="mw-page-title-main">Flavin adenine dinucleotide</span> Redox-active coenzyme

In biochemistry, flavin adenine dinucleotide (FAD) is a redox-active coenzyme associated with various proteins, which is involved with several enzymatic reactions in metabolism. A flavoprotein is a protein that contains a flavin group, which may be in the form of FAD or flavin mononucleotide (FMN). Many flavoproteins are known: components of the succinate dehydrogenase complex, α-ketoglutarate dehydrogenase, and a component of the pyruvate dehydrogenase complex.
