In enzymology a taxadiene 5alpha-hydroxylase (EC 1.14.99.37) is an enzyme that catalyzes the chemical reactiontaxa-411-diene + AH2 + O2 taxa-4(20)11-dien-5alpha-ol + A + H2OThe 3 substrates of this enzyme are taxa-411-diene an electron acceptor AH2 and O2 whereas its 3 products are taxa-4(20)11-dien-5alpha-ol the reduction product A 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.
