Pyrimidine dimer excision in exonuclease deficient mutants of Escherichia coli
Conference
·
OSTI ID:7208241
The rate of pyrimidine dimer excision has been measured in Escherichia coli strains deficient in exonuclease V, exonuclease VII, and the 5' ..-->.. 3' exonuclease of DNA polymerase I. The results suggest that a reduced level of the 5' ..-->.. 3' exonuclease of DNA polymerase I diminishes the rate of dimer excision and that an additional deficiency in exonuclease VII causes a significantly greater reduction in the cell's ability to remove dimers.
