Presentation

The Molecular Chaperone Networks research group at the Laboratory of Microbiology and Molecular genetics (LMGM-CBI) mainly focuses on the biology of molecular chaperone machines in bacteria. Genetics, molecular biology and biochemistry technics are used to identify new molecular chaperone functions and to pin point key interplay between major chaperones, such as DnaK/HSP70, DnaJ/HSP40, GroEL/HSP60, Trigger Factor or SecB, and other bacterial stress proteins, including Toxin-Antitoxin systems (see Figure). More recently, we have focused on SecB-like molecular chaperones in the human pathogen M. tuberculosis and revealed for the first time the control of a stress-responsive Toxin-Antitoxin system by molecular chaperones.
