Trihydroxypterocarpan dimethylallyltransferase

Trihydroxypterocarpan dimethylallyltransferase (EC 2.5.1.36, glyceollin synthase, dimethylallylpyrophosphate:3,6a,9-trihydroxypterocarpan dimethylallyltransferase, dimethylallylpyrophosphate:trihydroxypterocarpan dimethylallyl transferase, dimethylallyl-diphosphate:(6aS,11aS)-3,6a,9-trihydroxypterocarpan dimethyltransferase) is an enzyme with systematic name dimethylallyl-diphosphate:(6aS,11aS)-3,6a,9-trihydroxypterocarpan dimethylallyltransferase. This enzyme catalyses the following chemical reaction

(1) dimethylallyl diphosphate + (6aS,11aS)-3,6a,9-trihydroxypterocarpan

\rightleftharpoons

diphosphate + 2-dimethylallyl-(6aS,11aS)-3,6a,9-trihydroxypterocarpan

(2) dimethylallyl diphosphate + (6aS,11aS)-3,6a,9-trihydroxypterocarpan

\rightleftharpoons

diphosphate + 4-dimethylallyl-(6aS,11aS)-3,6a,9-trihydroxypterocarpan

Part of the glyceollin biosynthesis system in soy bean.
