[identification of the plasmid r1drd-19 region complementing the mutant phenotype recb- in escherichia coli k12 strain].plasmid r1-19 and its copy number mutants markedly increase the recombinational efficiency of a recb- strain of e. coli k12 and its resistance to the lethal action of uv and mitomycin c. these effects are associated with the appearance of a new atp-dependent exonuclease activity in recb- cells known to be deficient in the atp-dependent exonuclease v. using hybrid plasmids carrying different ecori fragments of r1-19 (in the psf124 vector), the gene(s) responsible for effect of r1-19 in recb-cells ...19853025684
