Repair of hydrogen peroxide-induced single-strand breaks in Escherichia coli deoxyribonucleic acid.
Near-ultraviolet (300 to 400 nm) irradiation of L-tryptophan yielded H2O2 (a toxic photoproduct) that was selectively lethal for rec and polA1 Escherichia coli mutants. H2O2 treatment of cells resulted in the induction of single-strand deoxyribonucleic acid breaks. These breaks were repaired to only...
