We tackle the challenge of bio-engineered light conversion using different approaches based on designed protein modifications. You can find more details on the our main approaches below.
MAIN RESEARCH LINES
Protein structure modulators for chromophore function modification. Conformational changes in Natural photosystems trigger changes in the chromophore energy states associated with key functions. Specific protein-dye interactions might have a role in boosting these backbone changes, but a scant understanding of their nature leads to an underestimation of their role. In our lab, we engineered bio-hybrid with key amino acids that act as structural modulators. We evaluate the impact of the structural modulators in the bio-hybrid conformation at different bio-exciton coupling regimes by assessing their effect at different levels, including folding landscape, photoactive molecule´s rotational freedom, and protein backbone dynamics. Using this information, we develop biophysical models that inform the structural modulator´s action mechanism and their role in the chromophore function modulation.
