Phytohemagglutinin, the lectin of the common bean Phaseolus vulgaris, has a high mannose and a modified (fucosylated) oligosaccharide on each polypeptide. Fractionation by high performance liquid chromatography of tryptic digests of (/sup 3/H)fucose or (/sup 3/H)glucosamine labeled phytohemagglutinin, followed by amino acid sequencing of the isolated glycopeptides, shows that the high mannose oligosaccharide is attached to Asn/sup 12/ and the modified oligosaccharide to Asn /sup 60/ of the protein. In animal glycoproteins, high mannose chains are rarely found at the N-terminal side of complex chains.
