We are interested in understanding how enzymes evolve new function and biochemical traits, and how are they adopted to their environment. We implement this knowledge to use directed enzyme evolution to design new tailor-made enzymes with improved characteristics that can be used for health environmental and agricultural applications, projects in the lab include:
1. Study the correlations between Quorum Quenching lactonases biochemical properties (e.g., specificity and stability), their environmental origin, and the ability to modulate bacterial chemical communication.
2. Identify and design new lactonases as anti-microbial treatments against bacterial infections in human and plants.
3. Design and encapsulate pesticide hydrolyzing enzymes.
4. Directed enzyme evolution of plastic degrading enzyme towards increased stability and activity with Polyethylene terephthalate, PET.
Enzymes are extremely potent biocatalysts capable of enhancing reaction rates by up to 1019-fold (kcat/knoncat). Despite their great proficiency, enzymes exhibit a remarkable evolutionary adaptability (evolvability). The lab is interested in understanding how enzymes evolve new function, for this we use phylogenetic and structural analysis in combination with directed enzyme evolution. Understanding the structural mechanisms that govern this molecular evolution processes can help us in better engineering tailor made enzymes with new properties for specific environmental, agricultural and industrial applications.
