Mutations that hamper dimerization of foot-and-mouth disease virus 3A protein are detrimental for infectivity.

abstract：:The foot-and-mouth disease virus (FMDV) capsid is highly acid labile, but introduction of amino acid replacements, including an N17D change in VP1, can increase its acid resistance. Using mutant VP1 N17D as a starting point, we isolated a virus with higher acid resistance carrying an additional replacement, VP2 H145Y,...
