Alignment of LTNP 5 Vif sequences. The product of LTNP 5 vif allele representing the consensus (allele 2) and the product of an allele representing the most divergent sequences from the group M, subgroup B, consensus (allele 3) were aligned to subgroup B consensus sequences (HIV-1). Each sequence represents a consensus of two clones from each of two independent PCRs. A period indicates conservation between subgroup B and LTNP 5 sequences.
