Figure 8. NrdAB exhibits activity during H2O2 stress only if YfaE is active.

Figure 8

Cells in anaerobic LB medium were diluted into aerobic medium at time zero, and the number of viable cells was monitored. (A) Viable cells during routine (unstressed) aerobic growth. MG1655 (wild type), JEM273 (ΔnrdEF), JEM290 (ΔyfaE), and JEM296 (ΔnrdEF ΔyfaE). (B) Viable cells during protracted H2O2 stress. Strains were LC106 (Hpx−), JEM646 (Hpx− ΔnrdEF), JEM325 (Hpx− ΔyfaE), and JEM475 (Hpx− ΔnrdEF ΔyfaE).
