protein O-linked glycosylation
protein o-linked glycosylation
A glycoprotein biosynthetic process starting with the covalent linkage of carbohydrate or carbohydrate derivative unit via a glycosidic bond to the oxygen atom of a serine, threonine, hydroxylysine, hydroxyproline or tyrosine side chain in a protein, which can be further elongated with the sequential addition of sugar units resulting in the formation of a protein O-linked glycan.
