What is Glycosylation?
Glycosylation refers to the enzymatic system that attaches glycans (sugar molecules) to proteins or lipids. This modification is very important for protein folding, balance, and serve as. There are two predominant different types of glycosylation: N-connected and O-associated.
N-Linked Glycosylation
In N-associated glycosylation, glycans attach to the nitrogen atom of asparagine residues in a protein. This kind is accepted in lots of secreted and membrane-certain proteins.
O-Linked Glycosylation
O-linked glycosylation Look at more info involves attaching glycans to the hydroxyl institution of serine or threonine residues. This model is mainly determined in mucins and other secreted proteins.
