Title: The isolation and the structure of new glycopeptide from blood group substances
Abstract: Three new glycopeptides with O-glycosidic and one glycopeptide with N-glycosylaminic carbohydrate-peptide linkages have been isolated after degradation of blood group substances (BGS). Their structure have been determined as O-(α-GalNAc)-Ser(I), O-(GalNAc)-(Pro)-Ser(II), O-(GalNAc 1 → 3 GalNAc)-(Thr-Ala)-Ser(III), N-(β-GlcNAc)-Asn(IV). The isolation of glycopeptide I confirmed α-configuration of O-glycosidic carbohydrate-peptide bonds. The structure of glycopeptide III with two galactosamine residues is in accordance with the data on the presence of hexosamine core of BGS carbohydrate chains.
