Asparagine carbohydrate units

Glycoproteins contain carbohydrate units covalently attached to their amino acid residues, mostly lysine or asparagine through N-glycosidic bonds (Fig. 2a). Less frequently is the attachment of sugars to serine and threonine side-... [Pg.22]

To establish the nature of the carbon-nitrogen bond of the carbohydrate-L-asparagine unit in glycoproteins, treatment of the synthetic derivatives 5 and 211 with hydrochloric acid was first studied in... [Pg.178]

Figure 4. Structures of the carbohydrate chains linked to protein in Saccharo-myces cerevisiae X2180 mannoprotein. Four types of mannose units are linked to serine (Ser) and threonine (Thr whereas a more complex polysaccharide chain is attached to asparagine (Asn). All anomeric linkages are a, except for the trisaccharide unit l3Man-> fiGNAc- ffGNAc- by which the polysaccharide is linked to asparagine. Figure 4.
