Overproduction of the epsilon subunit of DNA polymerase III counteracts the SOS mutagenic response of Escherichia coli.

It has been found that the mutator phenotype of the recA441 and recA730 strains that express the SOS response constitutively is suppressed by pIP1, a high-copy plasmid carrying the dnaQ gene encoding the 3'----5' exonuclease subunit (epsilon) of DNA polymerase III. We have constructed plasmid pIP11,...
