Figure 6
HIV-1 Gag p1-p6 and Env-V3 sequences. Translated amino acid sequences are shown for HIV-1 Gag p1-p6 region (panel A), and env-V3 (panel B). Sequences were aligned with the HXB2 reference sequence. Clone numbers are indicated. Strains B1 and B2 are the first and superinfecting virus from patient L, respectively. Strains B3 and B4 are the first and superinfecting virus from patient P, respectively. The 11 aa PTAPP repeat in clone B3.1 in Gag-p6 has been boxed. The 11th and 25th amino acid residues in Env-V3, associated with CXCR4 coreceptor use when positively charged, are indicated.
