Figure 3From: Functional conservation of HIV-1 Gag: implications for rational drug designNatural polymorphisms at 136 drug binding positions in 8 HIV-1 subtypes and CRFs. For each gag position, the HXB2 index is shown at the top, followed by the consensus amino acid and natural polymorphisms. Polymorphisms with proportions ≥ 5% are indicated with blue superscripts; orange otherwise.Back to article page
