Fig. 6

Non-covalent simulations, reporting the three-dimensional arrangement of the catalytic pentad in the four systems and its intra-pentad and pentad-DNA hydrogen bonds. WT: top-left panel; F187Y: top-right panel; G191A: bottom-left panel; and W242R: bottom-right panel. The residue–residue interactions are highlighted by a red line, while those occurring with the DNA are shown with a light blue line
