Glycosylation and Its Role in Protein Functionality
What is Glycosylation?
Glycosylation refers to the enzymatic process that attaches glycans—sugar molecules—to proteins or lipids. This publish-translational amendment can take place in diverse bureaucracy, including N-associated and O-connected glycosylation. It serves no longer in basic terms to stabilize proteins however additionally influences their characteristic, localization, and interaction with other biomolecules.
Types of Glycosylation
Importance of Glycosylation
The presence and structure of glycans can dictate different properties of proteins:
- Stability: Proper glycan platforms can escalate protein steadiness lower than physiological circumstances.
- Solubility: Glycans in many instances expand protein solubility with the aid of proposing hydrophilic surfaces.
