LITERATURE

O-glycan biosynthesis pathways and proposed O-glycan structures of selected glycosyltransferases, overview. Core 1 dominates the O-glycan repertoire. Core 1 can be further elongated by extended C1 beta3GnT3 enzyme to form extended core 1 structure, or be modified by C2 beta6GnT1 enzyme, EC 2.4.1.102, to form core 2 O-glycans. Regulation of O-glycan biosynthesis, overview. The extended C1 beta3GnT3 is competing withthe endogenous ST3Gal
