PubMed Abstract: Tuberculosis caused by is a leading cause of death world-wide. The PhoP protein is required for virulence and is part of the PhoPR two-component system that regulates gene expression. The NMR-derived solution structure of the PhoP C-terminal DNA-binding domain is reported. Residues 150 to 246 form a structured domain that contains a winged helix-turn-helix motif. We provide evidence that the transactivation loop postulated to contact RNA polymerase is partially disordered in solution, and that the polypeptide that connects the DNA-binding domain to the regulatory domain is unstructured.
