Abstract excerpt
A mutagenic oligonucleotide cassette was used to introduce single and tandem amino acid substitutions into the proteinase 3C coding region of an infectious poliovirus type 1 cDNA. The sites targeted for mutagenesis, residues 60, 61, and 66, are located within a putative helical loop structure whi...
