These data suggest that the ultraviolet sensitivity conferred by the uvrD mutation arises from inefficient removal of pyrimidine dimers or from failure to close incision breaks. The data are compatible with the notion that the uvrD+ gene produce affects the conformation of incised deoxyribonucleic acid molecules.

DNA mismatch repair (MMR) is a system for recognizing and repairing erroneous insertion, deletion, and mis-incorporation of bases that can arise during DNA replication and recombination, as well as repairing some forms of DNA damage.. Mismatch repair is strand-specific. During DNA synthesis the newly synthesised (daughter) strand will commonly include errors.

Förutom genförvärv via HGT förloras gener ofta via mutationsdeletioner, en process som 44 (mutH, mutL, mutS, uvrD) indikerar en mutatorspänning. Eftersom  uvrD-mediated stimulation of deletion was abolished by a lexAind3 mutation or by inactivation of either the recA, recF, recQ or ruvA genes. We conclude that (i) this stimulation requires SOS induction and (ii) tandem repeat recombination in uvrD mutants occurs via the RecF pathway. In uvrD+ cells, constitutive expression We have isolated three new mutations in uvrD that increase expression of the Escherichia coli SOS response in the absence of DNA damage. Like other uvrD (DNA helicase II) mutants, these strains are sensitive to UV irradiation and have high spontaneous mutation frequencies. These results were consistent with the idea that the uvrD, uvrE, recL, and pdeB mutations are alleles of the uvrD gene. In addition to the uvrD gene, lambda uvrD+ carried the corA gene that controls transport of Mg++, Mn++, and Co++ through the cell membrane.

The demonstration that mutants in the uvrA, uvrB or uvrC genes of E. coli are Mutants defective in just the uvrD gene are viable; hence DNA helicase II is 

To exclude mutations in other genes than the uvrD, we started from a uvrD3 mutant strain, and isolated uvrD-ts mutants by intragenic sup- pression of the uvrD3 mutation. A kinetic study of uvrD gene expression in vivo and the identifica- tion of a suppressor mutation in one of the UV-ts uvrD mutants will be also described. Mutations in the uvrD gene of Escherichia coli K-12 result in multiple phenotypes, including increased sensitivity to UV light and ionizing radiation, decreased ability for host cell reactivation, increased spontaneous mutation frequency and decreased rate of genetic recombination1-6. It has been shown, moreover, that double mutants having mutations in both uvrD and polA genes are Mutations in the uvrD gene that result in different phenotypes in respect to DNA repair and spontaneous mutation have been previously found.

Mutation of the uvrD gene of Escherichia coli is associated with an increased capacity for genetic recombination. The hyper-recombination effect is abolished by an additional mutation in lexA that limits synthesis of RecA protein and other gene products regulated by LexA repressor, and is not restored when increased synthesis of RecA protein is facilitated by a recAoc mutation.

The recF143 allele did not alter the phenotypes of dam mutants of Escherichia coli.

Like other uvrD (DNA helicase II) mutants, these strains are sensitive to UV irradiation and have high spontaneous mutation frequencies.

Regardless of whether a uvrD‐null or a uvrD252 mutation is used, the SOS response is highly induced in Pol IIIts uvrD double mutants.
