Abstract
⺠Molecular and biochemical characterization grape berry anthocyanidin 3-O-glucosyltransferase. ⺠Enzyme shows its strict regiospecificity for the 3-O-position of anthocyanidins and flavonols. ⺠Enzyme uses of UDP-glucose, but not UDP-galactose as a donor substrate. ⺠Kinetic analysis to show that rVL3GT preferentially glucosylates anthocyanidins in vitro. ⺠Gene expression coincides with post-veraison appearance of anthocyanidin 3GT enzyme activity.
