What is Glycosylation?
Glycosylation refers back to the enzymatic activity that attaches glycans (sugar molecules) to proteins or lipids. This modification is the most important for protein folding, stability, and characteristic. There are two essential styles of glycosylation: N-related and O-linked.
N-Linked Glycosylation
In N-associated glycosylation, glycans connect to the nitrogen atom of asparagine residues in a protein. This type is familiar in lots of secreted and membrane-certain proteins.
O-Linked Glycosylation
O-related glycosylation comes to attaching glycans to the hydroxyl staff of serine or threonine residues. This kind is frequently came upon in mucins and different secreted proteins.
