CYP716A52v2;
CYP716A12;
CYP16A75;
beta-amyrin 28-oxidase
Class

Sysname
beta-amyrin,[reduced NADPH---hemoprotein reductase]:oxygen oxidoreductase (28-hydroxylating)
Reaction(IUBMB)
beta-amyrin + 3 O2 + 3 [reduced NADPH---hemoprotein reductase] = oleanolate + 3 [oxidized NADPH---hemoprotein reductase] + 4 H2O (overall reaction) [RN:R10924];
(1a) beta-amyrin + O2 + [reduced NADPH---hemoprotein reductase] = erythrodiol + [oxidized NADPH---hemoprotein reductase] + H2O [RN:R10921];
(1b) erythrodiol + O2 + [reduced NADPH---hemoprotein reductase] = oleanolic aldehyde + [oxidized NADPH---hemoprotein reductase] + 2 H2O [RN:R10922];
(1c) oleanolic aldehyde + O2 + [reduced NADPH---hemoprotein reductase] = oleanolate + [oxidized NADPH---hemoprotein reductase] + H2O [RN:R10923]
Reaction(KEGG)
Substrate
beta-amyrin [CPD:C08616];
O2 [CPD:C00007];
[reduced NADPH---hemoprotein reductase] [CPD:C03024];
erythrodiol [CPD:C20945];
oleanolic aldehyde [CPD:C20946]
Product
oleanolate [CPD:C17148];
[oxidized NADPH---hemoprotein reductase] [CPD:C03161];
H2O [CPD:C00001];
erythrodiol [CPD:C20945];
oleanolic aldehyde [CPD:C20946]
Comment
A cytochrome P-450 (heme-thiolate) protein found in plants. The enzyme is involved in the biosynthesis of oleanane-type triterpenoids, such as ginsenoside Ro. The enzyme from Medicago truncatula (barrel medic) (CYP716A12) can also convert alpha-amyrin and lupeol to ursolic acid and betulinic acid, respectively. The enzyme from Maesa lanceolata (false assegai) (CYP16A75) does not catalyse the reaction to completion, resulting in accumulation of both intermediates.
