Differential activities of the SoxR protein of Escherichia coli: SoxS is not required for gene activation under iron deprivation.

Abstract excerpt

When Escherichia coli cells are under superoxide stress, proteins SoxR and SoxS, acting sequentially, control the expression of a set of repair and defense genes. One of these genes, fumC, encoding fumarase C, was reported to be also activated by iron deprivation in a soxRS-dependent manner. However, the same condition failed to induce the expression of a soxS'::lacZ fusion. The expression of acnA (aconitase A)...
