Extended Data Figure 7. GreB inactivation suppresses nusA sensitivity to genotoxic chemicals and UV.
a, Representative efficiencies of colony formation of wild-type (MG1655) and mutant E. coli cells in the presence of indicated amounts of NFZ and 4NQO. Cells were spotted on LB agar plates in serial tenfold dilutions and incubated at 30 °C for 24 h. b, Data from three independent experiments are presented as the mean ± s.e.m.; **P < 0.01. c, Representative efficiencies of colony formation of MDS42 and mutant E. coli cells in the presence of indicated amounts of mitomycin, 4NQO, NFZ and after UV irradiation. Cells were spotted on LB agar plates in serial tenfold dilutions and incubated at 30 °C for 24 h.
