Plasmidic recombination in Escherichia coli K-12: the role of recF gene function.

Abstract

Interplasmidic and intraplasmidic recombination proficiencies were determined in E. coli bacterial strains carrying rec mutations. Our results defined the role of recF gene function, recB, recC, and sbcB gene products (exonuclease V and exonuclease I) in plasmidic recombination in wild-type E. coli cells and in cells in which the recE recombination pathway is activated. RecF gene function is required for interplasmidic recombination regardless of the recB recC genotype. Intraplasmidic recombination is recF dependent in cells having a functional exonuclease V, but not in recB recC mutants. Exonuclease V activity inhibits both interplasmidic and intraplasmidic recombination via the recE pathway.
