Presentation

The Bacterial Pathogenesis group has a main laboratory in France (IBS Grenoble) and, since 2012, an ’antenna’ in Brazil (LNBio Campinas). This organization is supported by the CNRS, the CEA, and the University of Grenoble in the form of a ’Laboratoire International Associé’, and is supported by the São Paulo Foundation for Scientific Research (FAPESP). More information about the group in Campinas can be found through the links below :

Our group is interested in studying mechanisms employed by bacteria to initiate infection by tackling a number of different systems :

- The bacterial cell wall : macromolecular complexes and antibiotic development targets
- Virulence factors and secretion systems

Specialized techniques

We employ techniques ranging from molecular biology (site directed mutagenesis, polycistronic gene expression) and classical biochemistry (expression/purification of recombinant proteins, chemical cross-linking, enzymatic analyses) to X-ray crystallography in order to correlate the structure of a protein, protein-ligand or a multi-protein complex to its function either within the cell or during the infectious process.

Keywords

Bacterial infection, macromolecular machineries, structural biology.

Fellowships

The Bacterial Pathogenesis Group is searching for a Ph.D. candidate for a potential fellowship. The project involves the study of bacterial virulence factors and the search for novel small molecule inhibitors of infection.
