Induction of the feoB gene is necessary for downregulation of the Fur-repressed genes upon RstA activation .
Induction of the feoB gene is necessary for downregulation of the Fur-repressed genes upon RstA activation .
the RstA-dependent activation of feoAB transcription increased Fe uptake , whereas mutation of the RstA-binding sequences on the feoA promoter or deletion of the feoB gene abolished repression of Fur-regulated genes in cells .
Third increased Fe uptake , whereas mutation of the RstA-binding sequences on the feoA promoter or deletion of the feoB gene abolished repression of Fur-regulated genes in cells .
