FIG. 2.
RadA is synergistic with Holliday junction-processing genes in UV repair. UV survival curves are shown for E. coli strains both singly and multiply deficient for radA, recG, ruvA, and ruvC. All strains assayed for UV survival were derived from the AB1157 background. (A) AB1157, rec+ (▪); STL5280, radA1::kan (•); N2096, ruvAΔ63 (▴); CS140, ruvC53 (⧫); STL5046, ruvC53 radA1::kan (◊); STL5037, ruvAΔ63 radA1::kan (Δ); (B) AB1157, rec+ (▪); STL5280, radA1::kan (•); N4452, recGΔ265::cat (▴); STL6588, recGΔ265::cat radA1::kan (Δ); (C) AB1157, rec+ (▪); STL5280, radA1::kan (•); STL6586, recGΔ265::cat ruvC53 (◊); STL6640, recGΔ265::cat radA1::kan ruvC53 (⧫); STL6571, recGΔ265::cat ruvAΔ63(Δ); STL6592, recGΔ265::cat radA1::kan ruvAΔ63 (▴). Error bars indicate standard errors of the determinations.
