ENZYME entry: EC 1.14.13.112

Accepted Name
3-epi-6-deoxocathasterone 23-monooxygenase.
Alternative Name(s)
CYP90C1.
CYP90D1.
Reaction catalysed
  • 3-epi-6-deoxocathasterone + NADPH + O(2) <=> 6-deoxotyphasterol + NADP(+) + H(2)O
  • (22S,24R)-22-hydroxy-5-alpha-ergostan-3-one + NADPH + O(2) <=> 3-dehydro-6-deoxoteasterone + NADP(+) + H(2)O
Comment(s)
  • 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-5- alpha-ergostan-3-one and 3-epi-6-deoxocathasterone to 3-dehydro-6- deoxoteasterone and 6-deoxotyphasterol.
