FIG. 3.
Alignment of partial envelope protein sequences from multiple SIVagm isolates and from SIVagm.sab92018, SIVagm.sabD46, and SIVagm.ver644. PCR-derived env nucleotide sequences from SIVagm.ver644-infected vervet, and SIVagm.sab (92018 and D46)-infected sabaeus were translated, aligned with previously reported SIVagm env sequences (http://www.hiv.lanl.gov/content/hiv-db), and compared with a consensus sequence available on Los Alamos HIV Sequence Database. Dashes represent gaps and dots denote sequence identity to the SIVagm.sab consensus sequence. V3 designates a previously described hypervariable SIVagm env domain (51). NXT(S) (with X representing any amino acid except tryptophan [W]) and C represent putative N-linked glycosylation sites and cysteine residues, respectively. The N glycosylation sites are boxed.
