What is Glycosylation?
Glycosylation refers to the enzymatic activity that attaches glycans (sugar molecules) to proteins or lipids. This modification is significant for protein folding, balance, and serve as. There are two major kinds of glycosylation: N-related and O-related.
N-Linked Glycosylation
In N-related glycosylation, glycans attach to the nitrogen atom of asparagine residues in a protein. This style is typical in many secreted and membrane-sure proteins.
O-Linked Glycosylation
O-linked glycosylation comes to attaching glycans to the hydroxyl staff of serine or threonine residues. This shape is by and large came across in mucins and different secreted proteins.
