[Induction of prophage lambda during the irradiation of E. coli cells exposed to radiations of various LET].
Induction of lambda prophage in lysogenic E. coli cells exposed to ionizing radiation of different LET was studied as a function of dose I(D). Activities of pleiotropic RecA protein were shown to contribute to the shape of the I(D) curve. The experimental data were fitted by the function I(D) = alpha D(1-exp(-D0-1.D]exp(-beta D). Inducibility alpha increased with increasing LET which was related to the increased incidence of DNA lesions being a SOS-system call.
