Figure 3From: Genetic characterization of the cell-adapted PanAsia strain of foot-and-mouth disease virus O/Fujian/CHA/5/99 isolated from swineMultiple sequence alignment of amino acid sequences of the 3A coding region of 10 FMDV strains. The transmembrane domain contained amino acid substitutions at positions I61V and I76L (O/YUN/TAW/97), L69 M (O/AS/SKR/2002) and I72 M (O/SKR/2000 and O/Fujian/CHA/5/99) (A). The 93-102 amino acid deletions harbored in 3A of the porcinophilic phenotype of O/YUN/TAW/97 (B). The highly variable C-terminus was predicted probably due to the conformation of three-dimensional structure for 3A function (C).Back to article page
