What is Glycosylation?
Glycosylation refers back to the enzymatic manner that attaches glycans (sugar molecules) to proteins or lipids. This modification is relevant for protein folding, stability, and function. There are two predominant styles of glycosylation: N-linked and O-related.
N-Linked Glycosylation
In N-linked glycosylation, glycans attach to the nitrogen atom of asparagine residues in a protein. This model is regularly occurring in many secreted and membrane-sure proteins.
O-Linked Glycosylation
O-linked glycosylation comprises attaching glycans to the hydroxyl staff of serine or threonine residues. This form is more commonly observed in mucins and different secreted proteins.
