What is Glycosylation?
Glycosylation refers back to the enzymatic strategy that attaches glycans (sugar molecules) to proteins or lipids. This amendment is necessary for protein folding, stability, and operate. There are two essential forms of glycosylation: N-connected and O-related.
N-Linked Glycosylation
In N-related glycosylation, glycans connect to the nitrogen atom of asparagine residues in a protein. This model is regularly occurring in lots of secreted and membrane-certain proteins.
O-Linked Glycosylation
O-associated glycosylation comprises attaching glycans to the hydroxyl workforce of serine or threonine residues. This model is as a rule observed in mucins and other secreted proteins.
