A role of heat shock proteins for homologous recombination in Escherichia coli.
Effects of mutations in heat shock protein genes on homologous recombination in Escherichia coli were examined by measuring intra-molecular recombinations in the plasmid, pIK43. Recombination frequencies in the groES, groEL and dnaK mutants were decreased 6 to 21% of those of the isogenic wild type strain, at a sub-lethal temperature. Thus, the heat shock proteins GroES, GroEL and DnaK apparently participate in homologous recombination in Escherichia coli.
