What is Glycosylation?
Glycosylation refers to the enzymatic task that attaches glycans (sugar molecules) to proteins or lipids. This change is relevant for protein folding, steadiness, and serve as. There are two principal sorts of glycosylation: N-linked and O-associated.
N-Linked Glycosylation
In N-associated glycosylation, glycans connect to the nitrogen atom of asparagine residues in a protein. This variety is general in lots of secreted and membrane-certain proteins.
O-Linked Glycosylation
O-linked glycosylation entails attaching glycans to the hydroxyl crew of serine or threonine residues. This kind is most commonly determined in mucins and different secreted proteins.
