Average nonsynonymous and synonymous substitutions of each codon in the env V1-V5 region. Pairwise comparisons with SIVsmH635FC were performed using nucleic acid sequence data of clones amplified from plasma samples of SIVsmH635FC-infected macaques at 40/41 wpi. Numbers of nonsynonymous (non-syn) and synonymous (syn) substitutions per site were calculated with SNAP. The locations of seven nucleotide changes between SIVsmE543-3 and SIVsmH635FC are indicated by inverted triangles at the top. The V1 to V5 regions and GDPE motif are also indicated at the top. The codon numbers of env are shown at the bottom.
