Nucleotide identities of nonconserved position among natural isolates of HIV-2 and SIV superimposed on the two potential CGI conformations. The consensus branched (A) and extended (B) CGI structures from the analysis of 42 HIV-2 and SIV sequences from the HIV Sequence Compendium 2010 are indicated, with the proportions of alternative base pairs shown (Kuiken et al. 2010). Those nucleotides not absolutely conserved are boxed.
