3-Epi-6-deoxocathasterone 23-monooxygenase
3-Epi-6-deoxocathasterone 23-monooxygenase (EC 1.14.13.112, cytochrome P450 90C1, CYP90D1, CYP90C1) is an enzyme with systematic name 3-epi-6-deoxocathasterone,NADPH:oxygen oxidoreductase (C-23-hydroxylating).[1] This enzyme catalyses the following chemical reaction
- (1) 3-epi-6-deoxocathasterone + NADPH + H+ + O2 6-deoxotyphasterol + NADP+ + H2O
- (2) (22S,24R)-22-hydroxy-5alpha-ergostan-3-one + NADPH + H+ + O2 3-dehydro-6-deoxoteasterone + NADP+ + H2O
