Abstract
Approximately 10% of the total protein contained in Phaseolus vulgaris L. cv. Greensleeves seeds is composed of the glycoprotein lectin, phytohemagglutinin. We have investigated whether the presence of N‐linked oligosaccharide side chains is a prerequisite for the correct intracellular transport of this protein and whether unglycosylated phytohemagglutinin maintains its biological activities. Excised developing cotyledons were incubated in the presence of tunicamycin to prevent glycosylation “in vivo”, and the fate of the unglycosylated protein synthesized in such cotyledons determined. It was found that unglycosylated phytohemagglutinin reaches its normal site of accumulation, the protein bodies, and maintains erythro‐agglutinating and mitogenic activities.
