A close-up view of the interactions of 1-benzylimidazole and PBD150 with gQC and sQC. A, comparison of 1-benzylimidazole (BI) bound to gQC and sQC. The possible hydrophobic contacts are drawn with black dashed lines, with distances being indicated in angstroms. B, comparison of PBD150 bound to gQC and sQC. The possible hydrophobic contacts and hydrogen bonds are drawn with dashed lines colored in black and red, respectively, with distances being indicated in angstroms.
