The Laboratory of Molecular Bacteriology, Rega Institute, Department of Microbiology, Immunology and Transplantation, KU Leuven ( wishes to recruit 2 postdoctoral fellows in the following projects.

a. Secretory protein non-folding and folding and how it is regulated by intrinsic and extrinsic (e.g. chaperones) factors.

b. Structural dynamics of membrane associated/embedded channels and motors.

The lab studies protein trafficking through the Sec and the Type III secretion systems (Tsirigotaki 2018 Structure; Chatzi 2017 JCellBio; Portaliou 2018 EMBO J; Saio
 2014 Science 344, 6184; Gouridis 2013 Molecular Cell 52, 655; Chen 2011 Molecular Cell 44, 734; Gouridis 2009 Nature 462, 363; Gelis 2007
Cell 131, 756) and disordered/flexible human proteins involved in disease and chaperoning (e.g. Bcl-2 and IP3-regulate Ca2++ channel, prolyl oligopeptidase, -secretase; Monaco 2017 FEBS; Tsirigotaki 2017 SciReports). We have a very international lab environment and use multi-disciplinary approaches that combine molecular microbiology and genetics, recombinant DNA technologies, enzymology, protein chemistry, protein biophysics (including Hydrogen Deuterium Exchange/Native/nanoLC mass spectrometries, Isothermal Titration Calorimetry, Circular Dichroism, ensemble fluorescence, size exclusion chromatography coupled online to static and dynamic laser light scattering detection) structural biology, single molecule FRET. All methods are applicable on lab equipment.

Our lab MS, a Waters Synapt G2, is equipped with a nanoAcquity UPLC and HDX capabilities. We also have direct access to two Orbitraps: a Q-exactive and an Elite. We use MassLynx, PLGS, DynamiX and in-house developed software.
