A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 1.14.14.147

Accepted Name
3-epi-6-deoxocathasterone 23-monooxygenase.
Alternative Name(s)
CYP90C1.
CYP90D1.
Reaction catalysed
  • 3-epi-6-deoxocathasterone + [reduced NADPH--hemoprotein reductase] + O(2) <=> 6-deoxotyphasterol + [oxidized NADPH--hemoprotein reductase] + H(2)O
  • (22S,24R)-22-hydroxy-5-alpha-ergostan-3-one + [reduced NADPH--hemoprotein reductase] + O(2) <=> 3-dehydro-6-deoxoteasterone + [oxidized NADPH--hemoprotein reductase] + H(2)O
Comment(s)
  • A cytochrome P450 (heme-thiolate) protein 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.
  • Formerly EC 1.14.13.112.
