Fig. 2

a A schematic showing the domain organization of Pseudomonas syringae SsdA. PAAR: proline-alanine-alanine-arginine. The residue numbering is according to PDB entry 7jtu2. b Structure prediction by AlphaFold244 of full-length SsdA. The domains are color-coded as in (a). c The crystal structure of SsdAtox-ssDNA complex, viewed from three orthogonal orientations. The panel on the right shows the molecular surface of the protein colored according to electrostatic potential (blue: positive, red: negative).
