Abstract :
[en] Coumermycin A1 is a natural aminocoumarin that inhibits bacterial DNA gyrase, a member of the GHKL proteins superfamily. We report here the first cocrystal 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.
