Decreased transfer of pyrimidine dimers from parental to daughter DNA strands in UV-irradiated Escherichia coli deficient in DNA polymerase III.
The number of pyrimidine dimers (sites sensitive to UV-endonuclease from M. luteus) transferred at 43 degrees to daughter DNA strands during postreplication repair in UV-irradiated E. coli uvr A polCts was found to be decreased as compared to that after repair at 32 degrees. This indicates the involvement of DNA polymerase III in the sister DNA recombination in UV-irradiated E. coli.
