What is Glycosylation?
Glycosylation refers to the enzymatic task that attaches glycans (sugar molecules) to proteins or lipids. This modification is critical for protein folding, stability, and operate. There are two important styles of glycosylation: N-connected and O-related.
N-Linked Glycosylation
In N-connected glycosylation, glycans attach to the nitrogen atom of asparagine residues in a protein. This class is favourite in many secreted and membrane-sure proteins.
O-Linked Glycosylation
O-linked glycosylation involves attaching glycans to the hydroxyl staff of serine or threonine residues. This variety is more often than not determined in mucins and other secreted proteins.
