Effect of deletion of SOS-induced polymerases, pol II, IV, and V, on spontaneous mutagenesis in Escherichia coli mutD5.

Environmental and molecular mutagenesis - 1 Jan 2004

Abstract excerpt

The E. coli dnaQ gene encodes the epsilon subunit of DNA polymerase III (pol III) responsible for the proofreading activity of this polymerase. The mutD5 mutant of dnaQ chronically expresses the SOS response and exhibits a mutator phenotype. In this study we have constructed a set of E. coli AB1157 mutD5 derivatives deleted in genes encoding SOS-induced DNA polymerases, pol II, pol IV, and pol V, and estimated...
