title: Approximately 70% of fucose-labeled glycopeptides from the cell surface and cellular material of rat.
abstract: Approximately 70% of fucose-labeled glycopeptides from the cell surface and cellular material of rat fibroblasts (3Y1B cells) were hydrolyzed by endo-beta-N-acetylglucosaminidase D in the presence of neuraminidase, beta-galactosidase and beta-N-acetylglucosaminidase. Structure of the susceptible glycopeptides were found to be very similar to non-membrane glycopeptides of the complex heteropolysaccharide unit, such as the sialylated glycopeptides of thyroglobulin. On the other hand, the resistant glycopeptides were also refractory toward endo-beta-N-acetylglucosaminidase H and alpha-mannosidase, and appeared to be a mixture of glycopeptides with unique structures.
