Biophysical investigations of the Bordetella pertussis adenyl cyclase (CyaA) toxin. This project is performed by Dorothée Raoux Barbot, Alexis Voegele, Mélanie Huet, Mirko Sadi, Darragh O’Brien, Maryline Davi, Daniel Ladant and Alexandre Chenal. Past members of the group are Ana Cristina Sotomayor Pérez, Johanna C. Karst, Orso Subrini, Anna Wozniak, Audrey Hessel, Sylvain Debard, Sara Elisabetta Cannella and Véronique Yvette Ntsogo. Colleagues form other groups involved in the project are listed here. Our research interests are mainly focused on the study of the molecular mechanisms that underlying protein folding and membrane translocation of a bacterial toxin, the adenylate cyclase (CyaA) produced by Bordetella pertussis, the causative agent of whooping cough, which is currently in increasing incidence and represents a global public health concern. The study of CyaA offers the opportunity to explore various topics such as intrinsically disordered proteins (IDP), molecular crowding, protein-protein, protein-ligand and protein-membrane interactions.
