Abstract
This chapter describes the folding of synthetic homogeneous glycosylpolypeptides into glycoproteins depending on the position and number of glycosylation sites and oligosaccharide structures. To evaluate the role of oligosaccharides in protein folding, we synthesized small glycoprotein models, homogeneous misfolded glycoproteins, and erythropoietins. In addition to these chemical syntheses, this chapter introduces a unique method for 15N-labeling of synthetic glycoproteins to enable structural analysis. Based on experimental results, it can be suggested that N-glycans stabilize the structure of glycoproteins.
