Fig 7 — Coevolving pairs (colored as red) with minimum distance in one of the 22 structures were mapped in PDB:3J70 (A), CD4 bound, coloured cyan and PDB:3J5M (B), ligand free. All the subtype B gp120 founder pairs (S163-G164, S163-V169, S144m/h-M154) and one founder C pair (A133a-S138) were shown in PDB:3J5M. Subtype C founder pairs (I277-A281, E295-N334) and chronic pairs (A137-T138, A337-N339 and D185-N190k) were shown in PDB:3J70. The HXB2 strain was used as a reference to label the residues.
