Abstract excerpt
Genetic recombination in Escherichia coli is stimulated by a RecBCD enzyme-mediated event at DNA sequences known as Chi (chi) sites (5'-GCTGGTGG-3'). Previously, it was shown that chi acts to regulate the nuclease activity of RecBCD; here, we demonstrate that, under appropriate conditions, intera...
