In enzymology a sterol 14-demethylase (EC 1.14.13.70) is an enzyme that catalyzes the chemical reactionobtusifoliol + 3 O2 + 3 NADPH + 3 H+ 4alpha-methyl-5alpha-ergosta-81424(28)-trien-3beta-ol + formate + 3 NADP+ + 4 H2OThe 4 substrates of this enzyme are obtusifoliol O2 NADPH and H+ whereas its 4 products are 4alpha-methyl-5alpha-ergosta-81424(28)-trien-3beta-ol formate 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.
