Multiple sequence alignment of the PTAP region amino acid residues of the CAPRISA Cohort. One hundred and fifty sequences derived from 75 subjects were aligned with the subtype C consensus (Cons.) sequence. In the alignment, the dots represent sequence identity and the dashes sequence deletion. The PTAP core motifs are highlighted in the gray shade. The vertical dashed line demarcates the original (right side) and the duplicated (left side) PTAP motifs. The consensus subtype C gag sequence of 14 amino acids was used twice in the analysis for convenience
