Evidence of Divergent Amino Acid Usage in Comparative Analyses of R5- and X4-Associated HIV-1 Vpr Sequences

Figure 4

Sequence logos for Vpr regions 36–45 and 87–96. Both regions within the Vpr amino acid sequence included several peaks in amino acid diversity across multiple alphabets. They also contained all positions (36, 37, 41, 89, and 96) found to be statistically divergent using Jensen-Shannon divergence (boxed sequence logos).
