EC 1.14.13.112 Details
show Brenda entryEC number
1.14.13.112
Accepted name
3-epi-6-deoxocathasterone 23-monooxygenase
Reaction
(1) 3-epi-6-deoxocathasterone + NADPH + H+ + O2 = 6-deoxotyphasterol + NADP+ + H2O;;(2) (22S,24R)-22-hydroxy-5α-ergostan-3-one + NADPH + H+ + O2 = 3-dehydro-6-deoxoteasterone + NADP+ + H2O
Other name(s)
cytochrome P450 90C1,
CYP90D1,
CYP90C1
Systematic name
3-epi-6-deoxocathasterone,NADPH:oxygen oxidoreductase (C-23-hydroxylating)
Comment
This enzyme is involved in brassinosteroid biosynthesis. C-23 hydroxylation shortcuts bypass campestanol, 6-deoxocathasterone, and 6-deoxoteasterone and lead directly from (22S,24R)-22-hydroxy-5α-ergostan-3-one and 3-epi-6-deoxocathasterone to 3-dehydro-6-deoxoteasterone and 6-deoxotyphasterol [1].
