Project title: Molecular architecture of a DNA transfer machinery and its contribution to the dissemination of antibiotic resistance genes The transfer of large toxin and antibiotic resistance plasmids in Clostridium perfringens is mediated by the tcp conjugation locus. Functional genetic analysis of the tcp locus of the paradigm plasmid pCW3 has revealed that its gene products assemble into a multi-protein complex that distantly resembles a type 4 secretion system (T4SS). To understand how pCW3 is recognized and transferred we use an integrated structural biology framework combined to molecular genetic studies (Porter et al. 2012, Wisniewski, J. A. et al. 2017, Traore D. et al. 2018).
We continue to produce other components of the conjugative transfer system with the aim to further study them using a combination of Small Angle X-ray Scattering, Small Angle Neutron Scattering, X-ray crystallography and cryo-Electron Microscopy. The PhD student will further develop this research project taking advantage of the large instruments of the European Photon and Neutron (EPN) campus to unravel the molecular mechanism of conjugative DNA transfer. The project will also develop tools to combine Cryo-EM with neutron scattering techniques.
The ideal candidate should be familiar with molecular biology techniques (cloning, site directed mutagenesis) and recombinant protein production. Knowledge of biophysical tools is a plus but not essential.
Thesis environment The PhD student will be enrolled at Keele University. The work will be carried out 100 % at ILL (Grenoble, France) with visits to Keele University as needed. Coursework equivalence in Grenoble is in place.
