Method P.1452 right column top paragraph: "For [investigators'] first experiment, [they] transformed E. coli MC1061 with plasmid pPS2, a pBR322 derivative that expresses genes nrdA and nrdB of E. coli, known to encode the large and small subunits, respectively, of aerobic ribonucleotide reductase, leading to a doubling of the enzyme activity, as measured in cell-free extracts [ref 11]."
Comments P.1452 right column top paragraph: "As shown in Table 3, this caused the steady-state pools of dATP, dCTP and dTTP to increase about two-fold with respect to cells transformed by pBR322, accompanied by a smaller increase in the dGTP pool. However, these modest pool accumulations were accompanied by increases in frequency of rifampicin-resistant mutants of greater than 30-fold in three different experiments. Note that transformation of the host bacteria by pBR322 had no significant effect upon mutation frequency and only minor effects, if any, upon dNTP pools."
