In enzymology a 24-hydroxycholesterol 7alpha-hydroxylase (EC 1.14.13.99) is an enzyme that catalyzes the chemical reaction(24R)-cholest-5-ene-3beta24-diol + NADPH + H+ + O2 (24R)-cholest-5-ene-3beta7alpha24-triol + NADP+ + H2OThe 4 substrates of this enzyme are (24R)-cholest-5-ene-3beta24-diol NADPH H+ and O2 whereas its 3 products are (24R)-cholest-5-ene-3beta7alpha24-triol NADP+ and H2O.This enzyme belongs to the family of oxidoreductases specifically those acting on paired donors with O2 as oxidant and incorporation or reduction of oxygen.
