Project Focus: This study examines glycosylation which is a key post-translational modification and its impact on enzyme stability and activity. We will investigate two industrially relevant classes: glycosyl hydrolases and metalloproteases. Emphasis will be on glycosylation patterns to identify strategies that enhance structural integrity, protease resistance, and performance in home-care formulations.
Glycosylation is one of the most critical PTMs, involving the attachment of sugar moieties (glycans) to proteins. The two most common types are:
- N-linked glycosylation: Glycans are attached to the nitrogen atom of asparagine residues.
- O-linked glycosylation: Glycans are attached to the oxygen atom of serine or threonine residues.
Industrial Relevance: Enzymes are widely used across industries from pulp and paper to biofuels. In home-care applications, enzymes play a key role in sustainable cleaning, reducing reliance on fossil fuels and lowering the carbon footprint. However, many wild-type enzymes are unstable in home-care formulations due to surfactants and other cleaning ingredients like proteases, significantly lowering enzyme efficacy; therefore, methods to enhance stability are pertinent.
Hypotheses:
- Glycosylation enhances structural and proteolytic stability of enzymes.
- The type, size, and extent of glycosylation significantly influence enzyme activity and stability.
- Specific glycosylation patterns can optimize both stability and activity.
Methodology: To test these hypotheses, we will use glycoproteomics, biochemical assays, structural bioinformatics, and enzyme activity measurements.
