[The oxygen effect in E. coli cells. Role of the photoreactivated component in modifying the oxygen effect in E. coli

|January 1, 1984
Abstract:
A study was made of a contribution of photoreactivated lesions to the oxygen effect (OE) manifestation in cells of UV-sensitive E. coli WP2 uvrA6. It was shown that the contribution of the photoreactivated lesions depends upon radiation energy and gas conditions in which radiation is delivered. The OE value in the uvrA6-mutant may be modified in the irradiation conditions preventing induction of the photoreactivated lesions (gamma-irradiation in the presence of nigrosine, and X-irradiation).
