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.
