Accepted name: glyceollin synthase
Reaction: 2-(or 4-)dimethylallyl-(6a
S,11a S)-3,6a,9-trihydroxypterocarpan + NADPH + H + O + = glyceollin + NADP 2 + + 2 H O 2
For diagram of glyceollin biosynthesis (part 2),
Systematic name: 2-(or 4-)dimethylallyl-(6a
S,11a S)-3,6a,9-trihydroxypterocarpan,NADPH:oxygen oxidoreductase (cyclizing)
Comments: A heme-thiolate protein (
P-450). Glyceollins II and III are formed from 2-dimethylallyl-(6a S,11a S)-3,6a,9-trihydroxypterocarpan whereas glyceollin I is formed from the 4-isomer.
