Genome Replication and Regulation of Viral Gene ExpressionPicornavirus RNA Recombination Counteracts Error CatastrophePositive-strand RNA viruses produce vast amounts of progeny in very short periods of time via template-dependent RNA replication mechanisms. Template-dependent RNA replication, while efficient, can be disadvantageous due to error-prone viral polymerases. The accumulation of mutations in viral RNA genomes leads to error catastrophe. In this study, we substantiate long-held theories regarding the advantages and disadvantages of asexual...
Vaccines and Antiviral AgentsContribution of a Multifunctional Polymerase Region of Foot-and-Mouth Disease Virus to Lethal MutagenesisThe nuclear localization signal (NLS) of the foot-and-mouth disease virus (FMDV) polymerase includes residues that modulate the sensitivity to mutagenic agents. Here we have described a viable NLS mutant with an amino acid replacement that facilitates virus extinction by ribavirin. The corresponding polymerase shows increased incorporation of ribavirin triphosphate and local structural modifications that implicate the template entry...
