Résumé
Coumermycin A1 is a natural aminocoumarin that inhibits the bacterial DNA gyrase, a member of the GHKL proteins superfamily. We report here the first co-crystal structures of Gyrase B bound to coumermycin A1 revealing that one coumermycin A1 molecule traps simultaneously two ATP-binding sites. The inhibited dimers from different species adopt distinct sequence-dependent conformations, alternative to the ATP-bound form. These structures provide a basis for the rational development of coumermycin A1 derivatives for antibiotherapy and biotechnology applications.
