The Institut Pasteur’s BAG gathers the projects of the research units and platforms of the Institut Pasteur in Paris which are active in the structural biology field: Structural Microbiology (P.M. Alzari), Structural Dynamics of Macromolecules (M. Delarue), Structural Virology (F. Rey) and the Platform of Crystallography (A. Haouz). The non-exhaustive list of ongoing projects includes: - actinobacterial SepF, FtsZ and other cell division proteins; - central metabolic enzymes from actinobacteria; - DNA gyrase from Mycobacterium tuberculosis or model organisms; - Plasmodium proteases as drug targets; - bacterial models of pentameric ligand-gated ion channel family (pLGIC) receptors; - eukaryotic and archeal DNA polymerases and replisome proteins; - viral envelope proteins from pathogenic viruses, and their complexes with neutralizing antibodies; - enzymes and structural proteins from other human pathogens, supported by evolving national and international collaborations.
