In the same cells, intact ribophorins I and II also underwent O-linked glycosylation in the presence of BFA, but these molecules were modified only during a short time period immediately after their synthesis was completed, and the modification affected only a fraction of the newly synthesized polypeptides. To determine whether the apparent increase in the molecular masses of the truncated ribophorin I molecules that appear in BFA-treated cells reflects a processing of the N-linked oligosaccharide chain, the effect of endo H treatment on this protein was examined. ./cache/cord-355580-4pv1zu1g.txt ./txt/cord-355580-4pv1zu1g.txt
