3-Epi-6-deoxocathasterone 23-monooxygenase

3-Epi-6-deoxocathasterone 23-monooxygenase (, cytochrome P450 90C1, CYP90D1, CYP90C1) is an enzyme with systematic name 3-epi-6-deoxocathasterone,NADPH:oxygen oxidoreductase (C-23-hydroxylating). This enzyme catalyses the following chemical reaction


 * (1) 3-epi-6-deoxocathasterone + NADPH + H+ + O2 $$\rightleftharpoons$$ 6-deoxotyphasterol + NADP+ + H2O
 * (2) (22S,24R)-22-hydroxy-5alpha-ergostan-3-one + NADPH + H+ + O2 $$\rightleftharpoons$$ 3-dehydro-6-deoxoteasterone + NADP+ + H2O

3-Epi-6-deoxocathasterone 23-monooxygenase takes part in brassinosteroid biosynthesis.
