FIG. 4.

Sequence variability of Gag p17 and Env gp120 for subtypes B and C. Ribbon representation of gag p17 (A and B) and env gp120 (C and D) (Protein Data Bank accession code 1HIW and 1GC1, respectively), colored as follows: dN/dS ≤ 0.1, blue; dN/dS > 0.1 and ≤ 0.2, blue/purple; dN/dS > 0.2 and ≤ 0.25, purple; dN/dS > 0.25 and ≤ 0.4, pink; dN/dS > 0.4 and ≤ 0.5, red; dN/dS > 0.5 and ≤ 0.75, orange; dN/dS > 0.75 and ≤ 1.0, bright orange; dN/dS > 0.1 and ≤ 1.5, yellow; dN/dS > 1.5 and ≤ 2.5, pale yellow; dN/dS > 2.5, white, for subtype B (A and C) and subtype C (B and D). The figure was generated using the program PyMOL (available at http://www.pymol.org/). Although single chains are shown for protein structures, the correct oligomeric state was used for all analyses.
