In enzymology, a 4-(dimethylamino)phenylazoxybenzene reductase () is an enzyme that catalyzes the chemical reaction 4-(dimethylamino)phenylazobenzene + NADP+ 4-(dimethylamino)phenylazoxybenzene + NADPH + H+ Thus, the two substrates of this enzyme are 4-(dimethylamino)phenylazobenzene and NADP+, whereas its 3 products are 4-(dimethylamino)phenylazoxybenzene, NADPH, and H+. This enzyme belongs to the family of oxidoreductases, specifically those acting on other nitrogenous compounds as donors with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is 4-(dimethylamino)phenylazobenzene:NADP+ oxidoreductase. Other names in common use include N,N-dimethyl-p-aminoazobenzene oxide reductase, dimethylaminoazobenzene N-oxide reductase, NADPH-dependent DMAB N-oxide reductase, and NADPH:4-(dimethylamino)phenylazoxybenzene oxidoreductase.
