LIGPLOT symbols

• Ligand bonds are shown in bold lines while the thin bonds belong to the hydrogen-bonded residues from the protein.
• Hydrogen bonds are shown by dashed lines.
• Hydrophobic contacts made with the protein are indicated by the spoked arcs pointing towards the ligand. Corresponding spokes on the ligand atoms indicate which atoms are involved in these contacts.

Similarly, the atoms in the hydrogen-bonded groups involved in hydrophobic contacts are marked by spokes pointing in the direction of the contact atoms. For example, in 8gch, the C and CA atoms of the hydrogen-bonded group Gly 216 are involved in hydrophobic interactions with Trp 252 on the ligand.
• Chain identifiers are shown in parentheses.
