Shewanella are bacteria widespread in marine and brackish water environments and
emergent opportunistic pathogens. Their environmental versatility is highly dependent on …

Despite the abundance of iron in nature, iron acquisition is a challenge for life in general
because the element mostly exists in the extremely insoluble ferric (Fe 3+) form in oxic …

Siderophores make iron accessible under iron-limited conditions and play a crucial role in
the survival of microorganisms. Because of their remarkable metal-scavenging properties …

Shewanella oneidensis is an extensively studied bacterium capable of respiring minerals,
including a variety of iron ores, as terminal electron acceptors (EAs). Although iron plays an …

Iron, a major protein cofactor, is essential for most organisms but can simultaneously be
toxic. Iron homeostasis thus has to be effectively maintained under a range of iron regimes …

Ferric uptake regulator (Fur) is a transcriptional regulator playing a central role in iron
homeostasis of many bacteria, and Fur inactivation commonly results in pleiotropic …

The siderophore synthetic system in Shewanella species is able to synthesize dozens of
macrocyclic siderophores in vitro with synthetic precursors. In vivo, however, although three …

Abstract Background The Shewanella oneidensis MR-1 genome encodes a predicted
orphan DNA-binding response regulator, SO2426. Previous studies with a SO2426-deficient …

Dissimilatory Fe (III)‐reducing bacteria occupy a central position in a variety of
environmentally important processes, including the biogeochemical cycling of carbon and …

Iron is an essential element for most organisms. Microorganisms have evolved small
molecules with high affinity for Fe (III) named siderophores to obtain iron. SIPs (siderophore …
