[Increase in the fraction of non-repaired mutations in Escherichia coli cells, incubated in the absence of glucose after UV-irradiation].

Abstract excerpt

In E. coli WP2 trpE65 cells irradiated with UV-dose of 11 J/m2, the additional small portion of induced Trp+ mutations became resistant to photoreactivation or "dark" (excision) repair after a short-termed (10-30 min) postirradiation incubation of bacteria in a minimal medium deprived of glucose and tryptophan. Since protein synthesis could not proceed in those cells because of the lack of energy and tryptophan,...
