What is Glycosylation?
Glycosylation refers back to the enzymatic process that attaches glycans (sugar molecules) to proteins or lipids. This amendment is obligatory for protein folding, balance, and function. There are two important types of glycosylation: N-associated and O-associated.
N-Linked Glycosylation
In N-associated glycosylation, glycans attach to the nitrogen atom of asparagine residues in a protein. This fashion is commonly used in many secreted and membrane-bound proteins.
O-Linked Glycosylation
O-linked glycosylation consists of attaching glycans to the hydroxyl institution of serine or threonine residues. This form is routinely found out in mucins and other secreted proteins.
