Fig. 6.

Proximity of mutant and revertant residues on models of HIV CA. The locations of CTD helices 10 and 11 and residues H62 (red) and G208 (yellow) on pairs of CA proteins in HIV CA hexamers (PDB accession no. 3GV2) are depicted. Panel A is viewed roughly parallel to the plane of capsid coats, with the predicted outer capsid surface up and the inner surface down. Panel B is viewed roughly perpendicular to the capsid surface from the outside. Light and dark blue N-terminal domains and light and dark green C-terminal domains are as labeled.
