What is Glycosylation?
Glycosylation refers to the enzymatic activity that attaches glycans (sugar molecules) to proteins or lipids. This change is fundamental for protein folding, stability, and goal. There are two fundamental sorts of glycosylation: N-linked and O-related.
N-Linked Glycosylation
In N-connected glycosylation, glycans attach to the nitrogen atom of asparagine residues in a protein. This variety is primary in lots of secreted and membrane-bound proteins.
O-Linked Glycosylation
O-connected glycosylation contains attaching glycans to the hydroxyl team of serine or threonine residues. This kind is frequently came upon in mucins and other secreted proteins.
