Submicromolar hydrogen peroxide disrupts the ability of Fur protein to control free-iron levels in Escherichia coli

In aerobic environments, mutants of Escherichia coli that lack peroxidase and catalase activities (Hpx(−)) accumulate sub-micromolar concentrations of intracellular H(2)O(2). We observed that in defined medium these strains constitutively expressed members of the Fur regulon. Iron-import proteins, w...
