The translational elongation rate of E. coli subjecting to 0.5, 5 and 6 mM H₂O₂ treatment. (A) The translational elongation rate of three genes of E. coli cells before treatment as well as at various time points (5, 15, 30 min) after the addition of 0.5 mM H₂O₂. At the right panel, the translational elongation rate is shown together with the growth curve of E. coli cells subjecting to 0.5 mM H₂O₂ treatment. The data of translational elongation rate is the average of the values of three genes. (B) The translational elongation rate of three genes of E. coli cells before H₂O₂ treatment as well as at various time points (5, 40, 80 and 120 min) after the addition of 5 mM H₂O₂. At the right panel, the translational elongation rate is shown together with the growth curve of E. coli cells subjecting to 5 mM H₂O₂ treatment. The data of translational elongation rate is the average of the values of three genes. (C) The translational elongation rate of E. coli at various times points after the addition of 0.5, 1.5 and 5 mM H₂O₂. The data at time 0 corresponds to the normal value before H₂O₂ addition. (D) The induction curve of LacZ protein for E. coli cells growing in glucose minimal medium at two time points (5 min and 80 min) after the addition of 6 mM H₂O₂.
