From Wikipedia, the free encyclopedia
In the field of biochemistry, N-linked glycosylation is the attachment of a sugar molecule (known as glycan) to an amide nitrogen of asparagine (Asn) residue of a protein, giving rise to a glycoprotein. This type of linkage is important for both the structure [1] and function [2] of some eukaryotic proteins. The N-linked glycosylation process occurs in eukaryotes and widely in archaea, but very rarely in prokaryotes. The nature of N-linked glycans attached to a glycoprotein is determined by the protein and the cell in which it is expressed.[3] It also varies across species. Different species synthesises different types of N-linked glycoproteins.
