P benzoquinone reductase (NADPH)

In enzymology, a p-benzoquinone reductase (NADPH) (EC 1.6.5.6) is an enzyme that catalyzes the chemical reaction

The 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. The systematic name of this enzyme class is NADPH:p-benzoquinone oxidoreductase. This enzyme participates in gamma-hexachlorocyclohexane degradation.
