Repair of cross-linked DNA in Escherichia coli.
The repair of DNA containing interstrand cross-links in Escherichia coli was studied by following the temporal sequence of DNA-related metabolic events in cells exposed to psoralen plus light. Mutations in some genes controlling replication, recombination, and repair strongly influence these specific events. Results reported here are consistent with a cross-link repair mechanism involving sequential excision and recombination.
