Biocatalytic Production of Piceatannol-4'-O-Glucoside Using a Novel Glycosyltransferase SoUGT from Saponaria officinalis.
Piceatannol is a natural stilbene polyphenol with promising bioactivities, but its poor water solubility and low bioavailability limit industrial applications. In this study, a novel UDP-dependent glycosyltransferase, SoUGT, was identified from Saponaria officinalis for regioselective glycosylation of piceatannol. SoUG...
