Control of Escherichia coli superoxide dismutase (sodA and sodB) genes by the ferric uptake regulation (fur) locus.


The ferric uptake regulation (fur) gene product participates in regulating expression of the manganese- and iron-containing superoxide dismutase genes of Escherichia coli. Examination of beta-galactosidase activity coded from a chromosomal phi(sodA'-'lacZ) fusion suggests that metallated Fur protein acts as a transcriptional repressor of sodA (manganese… (More)
