Our previous studies showed that theN-linked sugar chains of most bovine glycoproteins from milk fat globule membranes (MFGM) contain the GalNAcβ1→4GlcNAc group [Satoet al. (1993)J. Biochem. 114, 890–900]. Since expression of the disaccharide structure is influenced by peptide sequences near the glycosylation sites [Smith and Baenziger (1992)Proc. Natl. Acad. Sci. USA 89, 329–333], the site-specificity of theN-acetylgalactosaminylated sugar chains was investigated using bovine butyrophilin, a major MFGM glycoprotein with known primary structure. Two glycopeptide fragments which contained theN-linked sugar chains linked to either Asn-55 or Asn-215 residue were obtained by digestion of the protein withAchromobacterprotease I. The sugar chains released from each glycopeptide by hydrazinolysis were reduced with NaB3H4. Structural analyses of the oligosaccharides by sequential exoglycosidase digestion and methylation analysis revealed that only complex-type sugar chains with the GalNAcβl→4GlcNAc structure are included in Asn-55-linked oligosaccharides, while only novel hybrid-type sugar chains detected previously in bovine MFGM glycoproteins are included in Asn-215-linked oligosaccharides. The results show that the glycosylation of butyrophilin occurs in a site-specific manner.
