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

Table 3

HIV-1 Vpr positions with high Jensen-Shannon divergence between R5- and X4-associated sequences. The calculated Jensen-Shannon divergence, along with the associated value in parentheses (in italics when ), is displayed for positions 36, 37, 41, 89, and 96.
