What is Glycosylation?
Glycosylation refers to the enzymatic strategy that attaches glycans (sugar molecules) to proteins or lipids. This amendment is quintessential for protein folding, steadiness, and function. There are two fundamental forms of glycosylation: N-associated and O-associated.
N-Linked Glycosylation
In N-linked glycosylation, glycans attach to the nitrogen atom of asparagine residues in a protein. This category is typical in lots of secreted and membrane-sure proteins.
O-Linked Glycosylation
O-associated glycosylation comes to attaching glycans to the hydroxyl neighborhood of serine or threonine residues. This shape is repeatedly came upon in mucins and different secreted proteins.
