560 The structural versatility required to accommodate binding of a broad range of ligands to different sites coupled with the wide distribution of oxidation-sensing Cys residues and low overall sequence similarity among MarR regulators, collectively suggest a model where ligand binding induces a conformational change in the homodimer that cannot be explained by a single sensing site and accompanying pathway of allosteric communication
