See all on WikipediaO-linked glycosylation is the attachment of a sugar molecule to the oxygen atom of serine (Ser) or threonine (Thr) residues in a protein. O-glycosylation is a post-translational modification that occurs after the protein has been synthesised. In eukaryotes, it occurs in the endoplasmic reticulum, Golgi … See more
O-N-acetylgalactosamine (O-GalNAc)
Addition of N-acetylgalactosamine (GalNAc) to a serine or threonine occurs in the See moreOne of the first and only examples of O-glycosylation on tyrosine, rather than on serine or threonine residues, is the addition of glucose to a tyrosine residue in glycogenin. Glycogenin is a glycosyltransferase that initiates the conversion of … See more
Proteoglycans consist of a protein with one or more sugar side chains, known as glycosaminoglycans (GAGs), attached to the oxygen of serine and threonine residues. GAGs … See more
