In Escherichia coli, the superoxide dismutase genes (sodA and sodB) sense the availability of Fe through the action of the fur locus [E. C. Niederhoffer, C. M. Naranjo, K. L. Bradley, J. A. Fee (1990) Control of Escherichia coli superoxide dismutases (sodA and sodB) genes by the ferric uptake regulation (fur) locus, J. Bacteriol. 172, 1930-1938]. Previous work from other laboratories has shown that a variety of metal chelators and of redox-active aromatic compounds can dramatically induce expression of sodA. Here we show that non-redox-active, non-metal-chelating aromatic compounds also enhance expression of a chromosomal sodA gene fusion and that these effects are strongly modulated by the Fur phenotype (Fur +/-) and by the availability of iron in the culture medium. The compounds studied were ethidium bromide, hemin, 2,2'-bipyridine, 1,10-phenantroline, 4,7-phenantroline, rhodamine B1, rhodamine 6G, and, for comparison to previous studies, Paraquat.
