Multiple alignments of the SV, HV1, and HV2 regions. Dots indicate identity to the top sequence shown, and gaps introduced to maximize homology are indicated by hyphens. The numbers at the top designate positions in a consensus sequence. (A) SV positions 30 to 40; (B) HV1 positions 81 to 112; (C) HV2 positions 159 to 207. The ordering of the sequences was by maximal visual similarity except for panel C, where the sequences were grouped by phylogenetic protein cluster.
