Hydroxyl Radicals Are Involved in Cell Killing by the Bacterial Topoisomerase I Cleavage Complex
Escherichia coli expressing SOS-inducing mutant topoisomerase I was utilized to demonstrate that covalent protein-DNA complex accumulation results in oxidative damage. Hydroxyl radicals were detected following mutant topoisomerase induction. The presence of the Fe(2+) chelator 2,2′-dipyridyl and an...
