Figure 2From: The extracellular death factor (EDF) protects Escherichia coli by scavenging hydroxyl radicals induced by bactericidal antibioticsHydroxyl radicals-scavenging activity of EDF (NNWNN) and its alanine substituted mutants. The hydroxyl radicals scavenging activity values represented the percentage of inhibition of deoxyribose degradation. Data were expressed as means ± S.D. (n = 3).Back to article page
