Moreover , dps are repressed by the Fe-responsive regulator Fur and induced under conditions of Fe limitation , whereas ftnA are maximally expressed when Fe is abundant .
Moreover , dps are repressed by the Fe-responsive regulator Fur and induced under conditions of Fe limitation , whereas bfr are maximally expressed when Fe is abundant .
These data suggest that dps are negatively regulated by Fur in Fe-rich-medium .
Whether Fur represses dps by indirect mechanisms remains to be determined .
Whether Fur represses dps by direct mechanisms remains to be determined .
hence are expressed under iron-replete conditions consistent with iron storage/detoxification roles , while dps are negatively regulated by Fur
