recF-dependent and recF recB-independent DNA gap-filling repair processes transfer dimer-containing parental strands to daughter strands in Escherichia coli K-12 uvrB.

The processes for repairing DNA daughter-strand gaps were studied in UV-irradiated uvrB, uvrB recB, uvrB recF, and uvrB recB recF cells of Escherichia coli K-12. The dimer-containing parental DNA was found to be joined to daughter strands during postreplication repair in all four strains examined. Therefore, both the major (recF-dependent) and the minor (recF recB-independent) gap-filling proce...

RecOR suppression of recF mutant phenotypes in Escherichia coli K-12.

The recF, recO, and recR genes form the recFOR epistasis group for DNA repair. recF mutants are sensitive to UV irradiation and fail to properly induce the SOS response. Using plasmid derivatives that overexpress combinations of the recO+ and recR+ genes, we tested the hypothesis that high-level expression of recO+ and recR+ (recOR) in vivo will indirectly suppress the recF mutant phenotypes me...

Effect of transcription on RecBC- and RecF-mediated recombination within the tryptophan operon of Escherichia coli K-12.

Recombination between tryptophan gene mutations within the trp operon was determined among transductants for an outside linked cysB marker under conditions of repression and derepression. These studies, carried out with recipient strains utilizing the RecBC or RecF pathway, or a combination of these pathways of recombination, demonstrate that transcription of trp genes as regulated by the trp r...

Molecular analysis of the recF gene of Escherichia coli.

We analyzed the nucleotide sequence of a 1.325-kilobase region of wild-type Escherichia coli containing a functional recF gene and six Tn3 mutations that inactivate recF. The analysis shows a potentially translatable reading frame of 1071 nucleotides, which is interrupted by all six insertions. A protein of 40.5 kilodaltons would result from translation of the open reading frame, and a radioact...

Recovery of DNA replication in UV-irradiated Escherichia coli requires both excision repair and recF protein function.

After UV doses that disrupt DNA replication, the recovery of replication at replication forks in Escherichia coli requires a functional copy of the recF gene. In recF mutants, replication fails to recover and extensive degradation of the nascent DNA occurs, suggesting that recF function is needed to stabilize the disrupted replication forks and facilitate the process of recovery. We show here t...
