ENZYME: 1.14.14.147

Entry

EC 1.14.14.147              Enzyme

Name

22alpha-hydroxysteroid 23-monooxygenase;
cytochrome P450 90C1;
CYP90D1;
CYP90C1;
3-epi-6-deoxocathasterone,[reduced NADPH---hemoprotein reductase]:oxygen oxidoreductase (C-23-hydroxylating);
3-epi-6-deoxocathasterone 23-monooxygenase

Class

Oxidoreductases;
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With reduced flavin or flavoprotein as one donor, and incorporation of one atom of oxygen into the other donor

Sysname

22alpha-hydroxysteroid,[reduced NADPH---hemoprotein reductase]:oxygen oxidoreductase (C-23-hydroxylating)

Reaction(IUBMB)

(1) 3-epi-6-deoxocathasterone + [reduced NADPH---hemoprotein reductase] + O2 = 6-deoxotyphasterol + [oxidized NADPH---hemoprotein reductase] + H2O [RN:R07792];
(2) (22S,24R)-22-hydroxy-5alpha-ergostan-3-one + [reduced NADPH---hemoprotein reductase] + O2 = 3-dehydro-6-deoxoteasterone + [oxidized NADPH---hemoprotein reductase] + H2O [RN:R07791]

Reaction(KEGG)

R07791 R07792;
(other) R07786 R07787

Substrate

3-epi-6-deoxocathasterone [CPD:C16251];
[reduced NADPH---hemoprotein reductase] [CPD:C03024];
O2 [CPD:C00007];
(22S,24R)-22-hydroxy-5alpha-ergostan-3-one [CPD:C15797]

Product

6-deoxotyphasterol [CPD:C15801];
[oxidized NADPH---hemoprotein reductase] [CPD:C03161];
H2O [CPD:C00001];
3-dehydro-6-deoxoteasterone [CPD:C15800]

Comment

A cytochrome P-450 (heme-thiolate) protein involved in brassinosteroid biosynthesis in plants. The enzyme has a relaxed substrate specificity, and C-23 hydroxylation can occur at different stages in the pathway. In Arabidopsis thaliana two isozymes, encoded by the CYP90C1 and CYP90D1 genes, have redundant activities.
