Molecular Recognition of CCR5 by an HIV-1 gp120 V3 Loop (original) (raw)
Figure 2
Important Intermolecular Polar Interactions;
Molecular graphics image of important polar interactions corresponding to the complex with the lowest average binding free energy. The figure shows the salt bridges and specific important hydrogen bonds. The V3 loop is shown in tube and in red color, and the residue moiety 16–20 is shown in fat tube representation. The CCR5 is shown in light gray transparent tube representation. The salt bridge and hydrogen bonds are denoted in dashed lines and the participating V3 loop and CCR5 residue moieties are shown in licorice; V3 loop and CCR5 residues are annotated in red and black, color respectively. Hydrogen atoms are omitted for clarity, and the V3 loop disulfide bridge is shown in fat transparent licorice representation.
