The wHTH DNA-binding domain of ZitR<sub>MG</sub>.

<p>The structure of holo-ZitR<sub>MG</sub> protein (this study, 6FI9, protomer A is shown as a green ribbon) and that of OhrR-<i>ohrA</i> complex (1Z9C, OhrR protomer A is shown as an orange ribbon and <i>ohrA</i> DNA colored in light-orange) have been superimposed, and a zoom on the Arg94 of OhrR wHTH DNA-binding domain is shown. Residues aligned between ZitR<sub>MG</sub> and OhrR are represented as ball-and-sticks with N colored in blue and O in red. Fully and moderately accessible residues are labelled in dark and light color respectively.</p>
