General Information
| General Information | Comment | Organism |
|---|---|---|
| metabolism | cytochrome P450 monooxygenase CYP716A254 is involved in oleanane-type triterpenoid saponins biosynthesis, i.e. the biosynthesis of oleanolic acid, which involves cyclization of 2,3-oxidosqualene to the oleanane-type triterpenoid skeleton, followed by a series of oxidation reactions catalyzed by cytochrome P450 monooxygenase (CYP450), Proposed biosynthetic pathway for oleanolic acid in Anemone flaccida, overview | Anemone flaccida |
| physiological function | cytochrome P450 monooxygenase CYP716A254 catalyzes the formation of oleanolic acid from beta-amyrin during oleanane-type triterpenoid saponins biosynthesis. Oleanolic acid is natural triterpenoid in plants with diverse biological activities | Anemone flaccida |
