What is Glycosylation?
Glycosylation refers to the enzymatic manner that attaches glycans (sugar molecules) to proteins or lipids. This modification is quintessential for protein folding, stability, and goal. There are two main kinds of glycosylation: N-related and O-linked.
N-Linked Glycosylation
In N-related glycosylation, glycans connect to the nitrogen atom of asparagine residues in a protein. This variety is conventional in lots of secreted and membrane-sure proteins.
O-Linked Glycosylation
O-connected glycosylation involves attaching glycans to the hydroxyl institution of serine or threonine residues. This shape is commonly came across in mucins and other secreted proteins.
