ROS-Mediated Signalling in Bacteria: Zinc-Containing Cys-X-X-Cys Redox Centres and Iron-Based Oxidative Stress

<table>An image showing the redox-sensing cysteine residues (Cys54 and Cys57) within the crystal structure of RslA from <i>Mycobacterium tuberculosis</i> (PDB: 3HUG). The coordinated zinc ion (shown as a violet ball) strongly contributes to the overall fold stability.</table>
