New insights into bacterial chemoreceptor arrays by electron cryotomography
Vendredi 16 novembre 2018 11:00
- Duree : 1 heure
Lieu : Salle des séminaires de l’IBS - 71, avenue des Martyrs - Grenoble
Orateur : Ariane BRIEGEL (Leiden University, The Netherlands)
Most motile bacteria contain a highly sensitive and adaptable sensory system composed of clusters of chemoreceptors. This chemosensory system is used to detect changes in nutrient concentrations, allows the cells to navigate towards preferential environments and is also involved
in host infection by some pathogenic bacteria. We use Electron Cryotomography (ECT) to study the three-dimensional architecture of the bacterial chemoreceptor arrays. ECT, in combination with genetics,
proteomics and molecular dynamics flexible fitting methods provides a powerful toolbox to unravel structure and function of the bacterial chemotaxis systems.
