Structural and functional basis of outer-membrane biogenesis

  • Master
  • Doctorate
  • Fall
  • Winter
  • With scholarship

Project description

The laboratory of Prof. Charles Calmettes focuses on the bacterial envelope biogenesis with a particular emphasis on the assembly of outer-membrane proteins in Gram-negative bacteria. The Master or PhD candidate will primarily work on characterizing a trans-envelope protein complex mediating the assembly of specific outer-membrane proteins, some of which contributing to virulence. The research project intends to dissect the molecular mechanism, and explore the substrate specificity of this novel assembly machinery. The candidate will be exposed to complementary methodologies combining biochemistry (protein expression, purification, activity assays), molecular biology (cloning, mutagenesis), proteomics (mass spectrometry), and structural biology (protein crystallography). Ultimately, this project aims at discovering novel anti-infective strategies against bacterial pathogens through the screening and identification of specific inhibitors that prevent virulence factors from bei

Financial support

INRS offers many scholarship programs. Every student-researcher benefits from a grant during their higher education studies.


The candidate should have a bachelor’s degree or a master’s degree (or equivalent for the Ph.D program) depending on the program of interest. Experience in molecular biology (cloning, site-directed mutagenesis), expression/purification of proteins, biochemistry (electrophoresis, enzymology), liposomes, structural biology, and mass spectrometry would be an asset. The candidate must master English (oral and writing)
