Zusammenfassung
Recently, we reported the characterization of the glycans attached at the 11 N-glycosylation sites of Hepatitis C virus E2 envelope glycoprotein by tandem mass spectrometry. Infections caused by Hepatitis C virus represent the main cause of liver diseases such as hepatitis, cirrhosis and hepatocellular carcinoma. The N-linked sugars consist primarily of high mannose glycans, with structures ranging from the minimal core structure, Man3GlcNAc2 (Man3) up to 12 hexose residues attached to the GlcNAc-ß(l 4)-GlcNAc core (depicted as Hex3Man9GlcNAc2). Furthermore, the site N41 (N423) was observed to contain complex type glycans with the structures Man3-GlcNAc and Man3-GlcNAcFuc, in addition to the high mannose population Man3 through Man6, while the site N48 (N430) was occupied exclusively with complex type glycans (Man3-Fuc, Man3-GlcNAcFuc and Man3-GlcNAc2Fuc). The present contribution summarizes our experimental observations upon the factors which may have an impact on the CID tandem mass spectra of glycopeptides.
