Structural Biology of Bacterial Macromolecular Complexes

Terradot Lab


Bacterial infections rely on the micro-organisms’ ability to adapt to its environment, subvert the immune system and multiply into its host. Our laboratory uses Biochemistry, X-ray Crystallography, Cryo-electron microscopy  and Biophysics techniques to investigate how bacteria infect human tissues. We focus our investigations on a particularly important one, Helicobacter pylori, associated with various human diseases, including gastric ulcers and stomach cancers. Our goal is to provide the molecular details of key infection steps to drive new antibiotics discovery. We use Structural Biology, a discipline that allows for a near atomic view of macromolecules and how they accomplish their functions.
