1.14.14.115
Accepted name
11-oxo-β-amyrin 30-oxidase
Reaction
11-oxo-β-amyrin + 3 O2 + 3 [reduced NADPH—hemoprotein reductase] = glycyrrhetinate + 3 [oxidized NADPH—hemoprotein reductase] + 4 H2O (overall reaction);;(1a) 11-oxo-β-amyrin + O2 + [reduced NADPH—hemoprotein reductase] = 30-hydroxy-11-oxo-β-amyrin + [oxidized NADPH—hemoprotein reductase] + H2O;;(1b) 30-hydroxy-11-oxo-β-amyrin + O2 + [reduced NADPH—hemoprotein reductase] = glycyrrhetaldehyde + [oxidized NADPH—hemoprotein reductase] + 2 H2O;;(1c) glycyrrhetaldehyde + O2 + [reduced NADPH—hemoprotein reductase] = glycyrrhetinate + [oxidized NADPH—hemoprotein reductase] + H2O
Other name(s)
CYP72A,
CYP72A154,
11-oxo-β-amyrin 30-monooxygenase
Systematic name
11-oxo-β-amyrin,[reduced NADPH—hemoprotein reductase]:oxygen oxidoreductase (30-hydroxylating)
Comment
A cytochrome P-450 (heme-thiolate) protein. The enzyme from the plant Glycyrrhiza uralensis (licorice) is involved in the biosynthesis of the triterpenoid saponin glycyrrhizin. The enzyme from the plant Medicago truncatula can also hydroxylate β-amyrin.
