Immunogenicity of the capsid precursor and a nine-amino-acid site-directed mutant of the 3C protease of foot-and-mouth disease virus coexpressed by a recombinant goatpox virus.

Abstract excerpt

The myristoylated capsid precursor mP1-2A of foot-and-mouth disease virus (FMDV), when expressed in mammalian cells and processed by the FMDV 3C protease, can self-assemble into virus-like particles (VLPs). In the present study, nine amino acids of the 3C protease were replaced by site-directed mutagenesis to create a mutant 3C protease, 9m3C. To coexpress mP1-2A and 9m3C and test the resulting proteolytic...
