What is Glycosylation?
Glycosylation refers to the enzymatic activity that attaches glycans (sugar molecules) to proteins or lipids. This amendment is indispensable for protein folding, balance, and serve as. There are two foremost different types of glycosylation: N-associated and O-linked.
N-Linked Glycosylation
In N-related glycosylation, glycans connect to the nitrogen atom of asparagine residues in a protein. This category is conventional in lots of secreted and membrane-sure proteins.
O-Linked Glycosylation
O-linked glycosylation contains attaching glycans to the hydroxyl staff of serine or threonine residues. This model is oftentimes located in mucins and different secreted proteins.
