The chromosome ofEscherichia colirecombines at low frequency when it is an intact circle but recombines at high frequency when it is broken, for example by X-rays, or when a linear DNA fragment is introduced into the cell during conjugation or transduction. The high recombinogenicity of double-strand (ds) DNA ends is attributable to RecBCD enzyme, which acts on ds DNA ends and is essential for recombination and ds DNA break repair. RecBCD enzyme initiates DNA unwinding at ds DNA ends, and its nuclease activity is controlled by Chi sites (5' G-C-T-G-G-T-G-G 3') in such a way that the enzyme produces a potent single-stranded DNA substrate for homologous pairing by RecA and single-stranded DNA binding proteins. We discuss a unifying model for recombination and ds DNA break repair, based upon the enzymic activities of these and other proteins and upon the behaviour ofE. colimutants altered in these proteins.
