In enzymology a p-benzoquinone reductase (NADPH) (EC 1.6.5.6) is an enzyme that catalyzes the chemical reactionNADPH + H+ + p-benzoquinone NADP+ + hydroquinoneThe 3 substrates of this enzyme are NADPH H+ and p-benzoquinone whereas its two products are NADP+ and hydroquinone.This enzyme belongs to the family of oxidoreductases specifically those acting on NADH or NADPH with a quinone or similar compound as acceptor.
