Beta-amyrin 11-oxidase

Beta-amyrin 11-oxidase (, CYP88D6) is an enzyme with systematic name beta-amyrin,NADPH:oxygen oxidoreductase (hydroxylating). This enzyme catalyses the following chemical reaction


 * beta-amyrin + 2 O2 + 2 NADPH + 2 H+ $$\rightleftharpoons$$ 11-oxo-beta-amyrin + 3 H2O + 2 NADP+ (overall reaction)
 * (1a) beta-amyrin + O2 + NADPH + H+ $$\rightleftharpoons$$ 11alpha-hydroxy-beta-amyrin + H2O + NADP+
 * (1b) 11alpha-hydroxy-beta-amyrin + O2 + NADPH + H+ $$\rightleftharpoons$$ 11-oxo-beta-amyrin + 2 H2O + NADP+

Beta-amyrin 11-oxidase requires cytochrome P450.
