Fig. 8.
Schematic diagram generated with LIGPLOT [19] showing the interactions of amino-acid residues residing on O1-helix with neighboring secondary structure elements of Gbst pol I LF (PDB code 1XWL). Asp718 (numbering of the full-length protein of Gbst pol I) corresponds to Asp422 (numbering of PB pol I LF) and Arg729 corresponds to Arg433, respectively. Hydrogen bonds are indicated by dashed lines. Hydrophobic contacts are shown by an arc with spokes radiating towards the ligand atom of contact
