Summary Metabolic labelling of immature jackbeans (Canavalia ensiformis) has been used in a pulse-chase study to determine changes in the glycosylation pattern of polypeptides during the assembly of Concanavalin A. In an analysis that allowed the identification of 7 intermediates, only the first precursor form of the lectin was labelled with D-[U-14C]-glucosamine. These results indicate that processing of the lectin involves a novel deglycosylation event in which an N-linked oligosaccharide is removed from a protein in the absence of proteolysis.
