Glycoproteins: glycan presentation and protein-fold stability

Abstract

Glycosylation of proteins has been shown to play a role in a variety of cellular events. Thanks to recent advances in obtaining conformational constraints across glycosidic linkages, structural characterisation of glycoproteins has improved considerably. It is now becoming apparent that N-glycosylation of a folded protein can have a significant stabilising effect on large regions of the backbone structure.
