Abstract
VEGF165 binding to endothelial cells is potentiated by glycosaminoglycans (GAGs). Here, we have investigated the impact of VEGF165 N-glycosylation on GAG binding. Although glycosylated VEGF165 bound to heparin with only slightly higher affinity than non-glycosylated VEGF165, the natural ligand heparan sulfate induced a conformational change only in the glycosylated protein. Unfolding studies of the VEGF proteins indicated a stabilising effect of heparin on the growth factor structure.
