Figure 6

Phylogenetic background of the aa at position one of p6. (A) SATé HIV-1/SIV/HIV-2 phylogeny in circular form. In the phylogenetic tree, the isolates have been colored corresponding to the first aa of p6. Isolates with a proline at position one of p6 are depicted in red, isolates in which p6 begins with leucine are colored green, and all other isolates are written in blue. The labeled rings indicate the virus species HIV-1 or HIV-2, respectively (outer), groups (middle) and subtypes (inner). (B) A total of 2088 representative sequences from the Los Alamos Sequence Database have been analyzed in silico regarding the first aa of p6. Depicted are the aa occurrences at position one of the p6 peptides of all HIV-1 groups and subtypes, SIVsm (including SIVmac sequences) and HIV-2. Sequences of p6, which begin neither with proline (red) nor with leucine (green), have been summarized as others (blue). The number of analyzed sequences is indicated in brackets and was set to 100% for each column.
