Peptidokeratan sulfates were retained by a concanavalin A-Sepharose column and readily eluted with 20mM methyl α-D-mannoside from the column. Linkage region-enriched glycopeptides, prepared by endo-β-galactosidase digestion of the peptidokeratan sulfates, behaved similarly to the peptidokeratan sulfates on the same affinity chromatography. Further, behaviors of both the peptidokeratan sulfates and the linkage region-enriched glycopeptides on pea lectin-Agarose columns were consistent with the results of the chromatography on concanavalin A-Sepharose. These findings confirmed the typical biantennary structure previously suggested for the linkage region on the basis of structural studies of the linkage region-enriched glycopeptides.
