[Modification of the radiosensitivity of E. coli cells by factors affecting the yield of photoreactivated damage].

Radiobiologiia - 1 Jan 2000

Seleva N G

Abstract excerpt

A study was made of the influence of irradiation conditions on the yield of the photoreactivable damages in radiosensitive mutants of E. coli cells (E. coli WP2). Pyrimidine dimers were shown to occur in exrA- and recA- mutants irradiated under anoxic conditions, the survival of these mutants being modified depending on cell genotype. The processes of direct excitation of the molecules were involved in the...
