Beta-amyrin 11-oxidase (EC 1.14.13.134 CYP88D6) is an enzyme with system name beta-amyrinNADPH:oxygen oxidoreductase (hydroxylating). This enzyme catalyses the following chemical reaction beta-amyrin + 2 O2 + 2 NADPH + 2 H+ 11-oxo-beta-amyrin + 3 H2O + 2 NADP+ (overall reaction)(1a) beta-amyrin + O2 + NADPH + H+ 11alpha-hydroxy-beta-amyrin + H2O + NADP+(1b) 11alpha-hydroxy-beta-amyrin + O2 + NADPH + H+ 11-oxo-beta-amyrin + 2 H2O + NADP+Beta-amyrin 11-oxidase requires cytochrome P450.
