Substrate
ent-kaur-16-en-19-oate [CPD:C11874];
[reduced NADPH---hemoprotein reductase] [CPD:C03024];
O2 [CPD:C00007];
ent-7alpha-hydroxykaur-16-en-19-oate [CPD:C11875];
gibberellin A12 aldehyde [CPD:C06093]
Product
gibberellin A12 [CPD:C11857];
[oxidized NADPH---hemoprotein reductase] [CPD:C03161];
H2O [CPD:C00001];
ent-7alpha-hydroxykaur-16-en-19-oate [CPD:C11875];
gibberellin A12 aldehyde [CPD:C06093]
Comment
A cytochrome P-450 (heme-thiolate) protein from plants. Catalyses three sucessive oxidations of ent-kaurenoic acid. The second step includes a ring-B contraction giving the gibbane skeleton. In pumpkin (Cucurbita maxima) ent-6alpha,7alpha-dihydroxykaur-16-en-19-oate is also formed.
