In enzymology, a NADPH dehydrogenase () is an enzyme that catalyzes the chemical reaction
NADPH + H<sup>+</sup> + acceptor NADP<sup>+</sup> + reduced acceptor
The 3 substrates of this enzyme are NADPH, H<sup>+</sup>, and acceptor, whereas its two products are NADP<sup>+</sup> 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
