The addition of oligosaccharides to particular residues on a protein This modification can be both co- translational and post- translational, occurring in the endoplasmatic reticulum and golgi Three different forms of glycosylation can be distinguished: N-linked oligosaccharides, O-linked oligosaccharides and glycosyl- phosphatidylinositol (GPI-) anchors [Glossary, Epicyte, 2002] http: //www epicyte com/glossary/glossary html
The reaction of a saccharide with a hydroxy or amino functional group to form a glycoside; especially the reaction with a protein or lipid to form a glycoprotein or glycolipid
The post-translational addition of carbohydrate groups to a molecule Glycosylation of proteins occurs via the amide group within the sequence Asn-X-Ser/Thr (or through the hydroxyl of the serine or threonine residue in the sequence); the product is a gly
The process by which proteins are modified by the addition of sugars (carbohydrates)
