Figure 3. Effect of oxyR disruption on the antioxidant ability of D. radiodurans.
(A) Catalase activities of R1, MOxyR, MOxyR_wtC, and MOxyR_sdC after H2O2 treatment (grey bar) or not (white bar). (B) ROS accumulate in four strains after H2O2 treatment (grey bar) or not (white bar). Data reported represent the average and standard deviations of three independent experiments.
