What is Glycosylation?
Glycosylation refers back to the enzymatic activity that attaches glycans (sugar molecules) to proteins or lipids. This modification is quintessential for protein folding, stability, and role. There are two foremost styles of glycosylation: N-related and O-associated.
N-Linked Glycosylation
In N-linked glycosylation, glycans attach to the nitrogen atom of asparagine residues in a protein. This type is primary in many secreted and membrane-sure proteins.
O-Linked Glycosylation
O-connected glycosylation consists of attaching glycans to the hydroxyl staff of serine or threonine residues. This kind is routinely located in mucins and other secreted proteins.
