The P1 protein consists of VP4 (aa 1–69), VP2 (aa 70–323), VP3 (aa 324–565) and VP1 (aa 566–862). Only amino acid residues with mutation were listed. Dots indicate amino acids identical to that of A-7
Conservative and non-conservative substitutions used for the computation of λ. Only amino acid mutations that are direct neighbors in the genetic code are considered in this analysis. A less stringend
