Abstract

The kinetics of SOS system induction in Escherichia coli PQ37 cells by gamma-irradiation has been studied by the SOS chromotest technique. It was shown that the synthesis of constitutive alkaline phosphatase is not immediately stopped in cells that suffered lethal damages from gamma-irradiation. The production of DNA damages inducing the SOS system was 0.021/Gy per genome. The SOS system was switched off approximately 200 min after gamma-irradiation. A correction is proposed to the calculation of the SOS system induction factor.
