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 change can take place in a lot of forms, which includes N-connected and O-related glycosylation. It serves not in basic terms to stabilize proteins however additionally affects their objective, localization, and interaction with other biomolecules.
Types of Glycosylation
Importance of Glycosylation
The presence and architecture of glycans can dictate more than a few residences of proteins:
- Stability: Proper glycan systems can escalate protein steadiness less than physiological situations.
- Solubility: Glycans on the whole develop protein solubility by way of presenting hydrophilic surfaces.
- Cellular Interactions: Glycans facilitate very good interactions among cells and their ambiance because of receptors.
