Tertiary structure of the P1 protein estimated with homology model. Four different amino acid residues on the viral capsid protein were labeled on the 3D structure of the EV71 capsid protein using Pymol software. VP1 (purple), VP2 (blue), VP3 (brown), and VP4 (yellow). Sites under positive selection were highlighted as cyan, pale cyan, red, and green, respectively. Letters and numbers refer to the amino acid residues and positions of VP1 in the prototype strain BrCr (U22521.1)
