Claim: NADPH—hemoprotein reductase, an enzyme that catalyzes the chemical reaction, belongs to the family of oxidoreductases and has two cofactors.
Evidence: In enzymology, a NADPH—hemoprotein reductase (EC ) is an enzyme that catalyzes the chemical reaction This enzyme belongs to the family of oxidoreductases, specifically those acting on NADH or NADPH with a heme protein as acceptor. It has 2 cofactors: FAD, and FMN.
