R.PabI-DNA interaction.

(a) Intermolecular hydrogen bonds between one R.PabI dimer and dsDNA. Hydrogen bonds between protomer A and the dsDNA are shown as green lines. Hydrogen bonds between protomer B and the dsDNA are shown as cyan lines. Residues of protomers A and B are colored green and cyan, respectively. (b,c) Intermolecular hydrogen bonds between R.PabI protomer A and dsDNA. Hydrogen bonds are shown as green dotted lines. Residues of protomer A and DNA bases are colored green and yellow, respectively. (d–f) Intermolecular hydrogen bonds between R.PabI protomer B and dsDNA. Hydrogen bonds are shown as blue dotted lines. Residues of protomer B are colored cyan. (g–i) R.PabI residues located above the major or minor groove of the dsDNA. The dsDNA is shown as a grey surface.
