- We use biophysical experimental techniques such as crystallography and SAXS to visualize at the atomic level the structure of molecules essential to life, such as DNA polymerases involved in DNA Repair and Cancer and ion channels involved in electric nerve signalling.
- We complement them with molecular and normal modes dynamics, so as to go beyond the essentially static pictures given by these methods.
- We also try to better understand the electrostatics of macromolecules and their interaction with the solvent, in order to be able to predict their binding properties.
- Our main goal is to design structure-inspired drugs (pharmacology) and re-design active site(s) to make them accept other substrates (synthetic biology).
Development of methods in computational structural biology
We are developing new computational methods to calculate the electrostatics of proteins, understand their dynamical properties and simulate transitions between two known conformations of the same macromolecule.
DNA Replication and Synthetic Biology
We work with archaeal DNA polymerases to make them accept xeno-nucleotides and synthesize variants of DNA and RNA in vivo.
DNA Repair and Cancer
We study the mechanism of DNA Repair of (DNA) Double Strand Breaks through the so-called Non-Homologous End Joining (NHEJ) process in mammals using x-ray crystallography and structural studies of pol mu and Tdt
Ligand-gated Ion channels
We study the structure and function of ligand-gated ion channels by X-ray crystallography to understand i) the gating mechanism (opening of the pore upon agonist binding) ii) the permeation mechanism (transport of ions through the pore) iii) […]
Inception – Institut Convergence for the study of Emergence of Pathology Through Individuals and Populations
Inception Goal The Inception’s goal is to develop a core structure to mobilize data resources, numerical sciences, and fundamental experimental biology in a range of health issues. Inception program uses Integrative Biology, Social Science […]
We have developed a new way to calculate electrostatics properties of biological macromolecules in a polarizable solvent: AquaSol. We can then compute the solvent density around proteins as well as their SAXS spectra: AquaSAXS.
