What is Glycosylation?
Glycosylation refers to the enzymatic activity that attaches glycans (sugar molecules) to proteins or lipids. This change is relevant for protein folding, stability, and perform. There are two principal forms of glycosylation: N-linked and O-linked.
N-Linked Glycosylation
In N-associated glycosylation, glycans attach to the nitrogen atom of asparagine residues in a protein. This category is common in many secreted and membrane-certain proteins.
O-Linked Glycosylation
O-linked glycosylation entails attaching glycans to the hydroxyl community of serine or threonine residues. This form is pretty much came upon in mucins and other secreted proteins.
