  1. The level of each protein in the untreated wild type E. coli is arbitrarily set as 100, and levels of proteins in other samples are expressed as relative to the level in the untreated E. coli. Results are the average of three to five independent experiments (biological repeats) with standard deviation. † Level differs significantly from that of untreated wild type E. coli; and § level differs significantly from that of wild type E. coli treated with H2O2 (p < 0.05, Student's t-test).
