Function

VESTR_MEDSA Stereospecific enzyme that catalyzes the NADPH-dependent reduction of (3R)-vestitone to (3R,4R)-4'-methoxyisoflavan-2',4,7-triol (DMI). Has no activity with (3S)-vestitone. Catalyzes the penultimate step in the biosynthesis of the phytoalexin medicarpin, and thereby contributes to plant defense reactions.^{[1] [2] [3]}
