Halobacterium uvrA, uvrB, uvrC, and uvrAuvrC mutants are sensitive to UV light. Data represent the averages of at least three independent survival experiments. Standard deviations between all uvr mutants and DJC501 (uvr⁺) were non-overlapping. All manipulations and incubations were performed in yellow light or in the dark to prevent photoreactivation.
