In enzymology a taxane 13alpha-hydroxylase (EC 1.14.13.77) is an enzyme that catalyzes the chemical reactiontaxa-4(20)11-dien-5alpha-ol + NADPH + H+ + O2 taxa-4(20)11-dien-5alpha13alpha-diol + NADP+ + H2OThe 4 substrates of this enzyme are taxa-4(20)11-dien-5alpha-ol NADPH H+ and O2 whereas its 3 products are taxa-4(20)11-dien-5alpha13alpha-diol 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.
