Efficient glycosyltransferases from A. membranaceus enable biosynthesis of bioactive pterocarpan glycosides

A research team has identified two highly efficient glycosyltransferases, AmGT28 and AmGT44, from Astragalus membranaceus, which convert medicarpin to medicarpin 3-O-glucoside and show a preference for pterocarpans over isoflavonoids.
