Lignans are a class of diphenolic nonsteroidal phytoestrogens often found glycosylated in planta. Flax seeds are a rich source of secoisolariciresinol diglucoside (SDG) lignans. Glycosylation is a process by which a glycosyl group is covalently attached to an aglycone substrate and is catalyzed by uridine diphosphate glycosyltransferases (UGTs). | Identification and functional characterization of a flax UDP-glycosyltransferase glucosylating secoisolariciresinol SECO into secoisolariciresinol monoglucoside SMG and diglucoside SDG
