Fig. 4

a Crystal structure of the SsdAI-SsdAtox complex (PDB ID: 7jtu)2. The molecular surface is shown for SsdAI, colored according to electrostatic potential (blue: positive, red: negative). The side chains of acidic residues positioned similarly to DNA backbone phosphates are labeled. b SsdAtox-DNA complex in the same orientation as in (a). c Structure of the SsdAI-SsdAtox complex as in (a), after a 90° rotation. Some of the SsdAI residues are shown in sticks and visible through a semi-transparent surface. d SsdAtox-DNA complex in the same orientation as in (c).
