Understanding Glycosylation

What is Glycosylation?

Glycosylation refers back to the enzymatic task with the aid of which carbohydrates (glycans) are covalently attached to proteins or lipids. This amendment plays a crucial function in cell features consisting of cell phone signaling, immune response, and protein folding.

Types of Glycosylation

  • N-related Glycosylation: Occurs when glycans attach to nitrogen atoms in asparagine residues.
  • O-linked Glycosylation: Involves attachments to the oxygen atom in serine or threonine residues.
  • C-related Glycosylation: A less commonplace model in which sugars are associated immediately to carbon atoms on tryptophan residues.
  • Why is Glycosylation Important?

    The presence and constitution of glycans can effect protein conformation, organic sport, or even immunogenicity. Understanding these buildings is significant for developing productive therapeutics.
