Deduced amino acid residues of the V3 region derived from CRF01_AE, CRF07_BC, and the B subtype in HIV-1 strains in Harbin City versus the reference sequences (HXB2). The deduced amino acids are shown by the single-letter code. Tetramers on the tip of the V3 loop are indicated on the consensus sequence by open boxes.
