abstract：:Contemporary glycobiology reflects the intense interest in glycoproteins and their biological roles. Addition of saccharides by N- or O-glycosylation is precise rather than random and forms a uniquely interactive molecular surface. We designate these well conserved glycomotifs as glycomodules to emphasize their functi...
