N-linked glycosylation

N-linked glycosylation

N-linked glycosylation-High Mannose

N-linked glycosylation, is the attachment of a glycan consisting of several sugar molecules to a nitrogen atom (the amide nitrogen of an asparagine (Asn) residue of a protein). This type of linkage is important for both the structure and function of many eukaryotic proteins. The N-linked glycosylation process occurs in eukaryotes and widely in archaea, but very rarely in bacteria. The nature of N-linked glycans attached to a glycoprotein is determined by the protein and the cell in which it is expressed. It also varies across species. Different species synthesize different types of N-linked glycans. The major fractions consisted of "high-mannose type" oligosaccharides containing five to nine mannose residues.

N-linked glycosylation-Complex

N-linked glycosylation, is the attachment of a glycan consisting of several sugar molecules to a nitrogen atom (the amide nitrogen of an asparagine (Asn) residue of a protein). This type of linkage is important for both the structure and function of many eukaryotic proteins. The N-linked glycosylation process occurs in eukaryotes and widely in archaea, but very rarely in bacteria. The nature of N-linked glycans attached to a glycoprotein is determined by the protein and the cell in which it is expressed. It also varies across species. Different species synthesize different types of N-linked glycans. N-linked glycosylation with Bi- and tri-antennary branches with the ubiquitous building block GalĪ²1-4GlcNAc, are called complex.

N-linked glycosylation-hybrid

N-linked glycosylation, is the attachment of a glycan consisting of several sugar molecules to a nitrogen atom (the amide nitrogen of an asparagine (Asn) residue of a protein). This type of linkage is important for both the structure and function of many eukaryotic proteins. The N-linked glycosylation process occurs in eukaryotes and widely in archaea, but very rarely in bacteria. The nature of N-linked glycans attached to a glycoprotein is determined by the protein and the cell in which it is expressed. It also varies across species. Different species synthesize different types of N-linked glycans.N-linked glycosylation with Bi- and tri-antennary branches with the ubiquitous building block GalĪ²1-4GlcNAc, and mannose residues are called hybrid.
