ID 1.14.14.126 DE beta-amyrin 28-monooxygenase. AN beta-amyrin 28-oxidase. AN CYP16A75. AN CYP716A12. AN CYP716A52v2. CA beta-amyrin + 3 O2 + 3 reduced [NADPH--hemoprotein reductase] = 4 H(+) + CA 4 H2O + oleanolate + 3 oxidized [NADPH--hemoprotein reductase]. CC -!- A cytochrome P450 (heme-thiolate) protein found in plants. CC -!- The enzyme is involved in the biosynthesis of oleanane-type CC triterpenoids, such as ginsenoside Ro. CC -!- The enzyme from Medicago truncatula (barrel medic) (CYP716A12) can CC also convert alpha-amyrin and lupeol to ursolic acid and betulinic CC acid, respectively. CC -!- The enzyme from Maesa lanceolata (false assegai) (CYP16A75) does not CC catalyze the reaction to completion, resulting in accumulation of CC both intermediates. CC -!- Formerly EC 1.14.13.201.
