What is Glycosylation?
Glycosylation refers back to the enzymatic procedure that attaches glycans (sugar molecules) to proteins or lipids. This amendment is important for protein folding, stability, and serve as. There are two fundamental different types of glycosylation: N-related and O-related.
N-Linked Glycosylation
In N-connected glycosylation, glycans connect to the nitrogen atom of asparagine residues in a protein. This sort is usual in many secreted and membrane-certain proteins.
O-Linked Glycosylation
O-associated glycosylation consists of attaching glycans to the hydroxyl team of serine or threonine residues. This type is ceaselessly chanced on in mucins and different secreted proteins.
