ID   1.14.14.147
DE   22alpha-hydroxysteroid 23-monooxygenase.
AN   3-epi-6-deoxocathasterone 23-monooxygenase.
AN   CYP90C1.
AN   CYP90D1.
CA   (1) 3-epi-6-deoxocathasterone + O2 + reduced [NADPH--hemoprotein
CA   reductase] = 6-deoxotyphasterol + H(+) + H2O + oxidized [NADPH-
CA   -hemoprotein reductase].
CA   (2) (22S,24R)-22-hydroxy-5alpha-ergostan-3-one + O2 + reduced [NADPH-
CA   -hemoprotein reductase] = 3-dehydro-6-deoxoteasterone + H(+) + H2O +
CA   oxidized [NADPH--hemoprotein reductase].
CC   -!- A cytochrome P450 (heme-thiolate) protein involved in brassinosteroid
CC       biosynthesis in plants.
CC   -!- The enzyme has a relaxed substrate specificity, and C-23
CC       hydroxylation can occur at different stages in the pathway.
CC   -!- In Arabidopsis thaliana two isozymes, encoded by the CYP90C1 and
CC       CYP90D1 genes, have redundant activities.
CC   -!- Formerly EC 1.14.13.112.
