Site-directed mutagenesis of proteinase 3C results in a poliovirus deficient in synthesis of viral RNA polymerase.
We used a synthetic double-stranded oligonucleotide to introduce amino acid substitutions into the proteinase 3C region of a poliovirus type 1 cDNA clone. The six different mutant viruses recovered exhibited a small-plaque phenotype when assayed on HeLa cells. Further investigation revealed that all...
