Glycosylation and Its Role in Protein Functionality
What is Glycosylation?
Glycosylation refers to the enzymatic technique that attaches glycans—sugar molecules—to proteins or lipids. This submit-translational modification can arise in a number types, which include N-associated and O-related glycosylation. It serves no longer in basic terms to stabilize proteins yet also impacts their goal, localization, and interaction with other biomolecules.
Types of Glycosylation
Importance of Glycosylation
The presence and shape of glycans can dictate a great number of homes of proteins:
- Stability: Proper glycan buildings can escalate protein balance lower than physiological conditions.
