REACTION DIAGRAM
2-(or 4-)dimethylallyl-(6aS,11aS)-3,6a,9-trihydroxypterocarpan + [reduced NADPH-hemoprotein reductase] + O2
glyceollin + [oxidized NADPH-hemoprotein reductase] + H2O
-
enzyme catalyzes an NADPH-dependent and oxygen-dependent cyclization of a mixture of 2- and 4-dimethylallylglycinols to the glyceollin isomers I-III
glyceollin isomers I-III, glyceollin isomer I is formed from 4-dimethylallylglycinol and glyceollin isomers II and III from 2-dimethylallylglycinol
