What is Glycosylation?
Glycosylation refers to the enzymatic method that attaches glycans (sugar molecules) to proteins or lipids. This modification is imperative for protein folding, balance, and role. There are two important varieties of glycosylation: N-associated and O-connected.
N-Linked Glycosylation
In N-connected glycosylation, glycans attach to the nitrogen atom of asparagine residues in a protein. This style is time-honored 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 variety is commonly came across in mucins and other secreted proteins.
