A microsomal fraction of elicitor‐challenged bean (Phaseolus vulgaris) cell suspension cultures catalyses the prenylation of 3,9‐dihydroxypterocarpan (DHP) to 3,9‐dihydroxy‐10‐dimethylallylpterocarpan (phaseollidin) with dimethylallylpyrophosphate (DMAPP) as the prenyl donor. K m values for DMAPP and DHP are in the range 1–3 μM. Strong product inhibition with phaseollidin and phaseollin is observed.
