The UV sensitivity of the dnaN159 strain is epistatic with mutations that impair recFOR function. Survival following the indicated dose of UV irradiation was measured by plating serial dilutions as previously described (29). The strains examined are derivatives of RW118 [thr-1 araD139 Δ(gpt-proA)62 lacY1 tsx-33 glnV44(AS) galK2(Oc) hisG4(Oc) rpsL31 xylA5 mtl-1 argE3(Oc) thi-1 sulA211] (15): RM149 (dnaN+ ΔuvrB::cat), RM150 (dnaN159 ΔuvrB::cat), RM151 (dnaN+ ΔuvrB::cat ΔrecO1504::Tn5), RM152 (dnaN159 ΔuvrB::cat ΔrecO1504::Tn5), RM163 (dnaN+ ΔuvrB::cat ΔrecR252::Tn10∼9), and RM164 (dnaN159 ΔuvrB::cat ΔrecR252::Tn10∼9). The results shown represent the average of two independent experiments, each done in duplicate. The error bars represent the range.
