Biophysique des métalloprotéines

Biophysics of metalloproteins


To perform our research, we use various techniques ranging from biochemistry to advanced biophysical and computational methods. Some details can be found below on the different expertise available in the team.


We perform heterologuous expression of desired proteins in Escherichia coli. Biochemical methods of characterization and identification of proteic domains are used. We prepare on site protein samples for biophysical charaterization.



Electron Paramagnetic Resonance (EPR) is a central technique for characterizing paramagnetic species. In the field of Life Sciences, it is particularly well suited for molecular analysis of biological systems, their functions and interactions.

DFT and MD calculations

In addition to experimental studies, we perform molecular modeling calculations based on quantum chemistry methods (Density functional theory, hybrid methods…) and molecular dynamic simulations. 
Calculated EPR properties such as g and hyperfine tensors are computed and compared with experimental ones to determine the structure of EPR-detected species.

Spin labelling

Site-Directed Spin Labeling (SDSL) combined to Electron Paramagnetic Resonance (EPR) is a powerful technique used since the 90s to study structural modification of proteins in solution. The technique is based on the introduction of a spin label (usually a nitroxide) on a specific position (usually introduced by mutagenesis) in the protein.
