Figure 7.

Structural model of the N-terminal domain of HIV-1 CA with G116E substitution. Panel A shows the template structure of the N-terminal domain of the HIV-1 CA; panel B shows the model of the domain structure with the G116E mutation. The ribbons represent the protein backbone; G and E on the 116^th position with their side chains are shown in red spheres. Panels C and D show surface views of the template and model structures respectively with the 116^th position indicated in red. The loops between α-helices 4 and 5 (L4/5) and 6 and 7 (L6/7) are labeled.
