Control of metal homeostasis is essential for life in all kingdoms. In most prokaryotic
organisms the FUR (ferric uptake regulator) family of transcriptional regulators is involved in …

The transition or d-block metal ions manganese, iron, cobalt, nickel, copper, zinc and to a
more specialized degree molybdenum, tungsten, and vanadium have been shown to be …

Deinococcus bacteria are famous for their extreme resistance to ionising radiation and other
DNA damage-and oxidative stress-generating agents. More than a hundred genes have …

Iron is both an essential nutrient for the growth of microorganisms, as well as a dangerous
metal due to its capacity to generate reactive oxygen species (ROS) via the Fenton reaction …

This minireview presents recent advances in our understanding of iron oxidation and
homeostasis in acidophilic Bacteria and Archaea. These processes influence the flux of …

Bacterial transition metal homoeostasis or simply 'metallostasis' describes the process by
which cells control the intracellular availability of functionally required metal cofactors, from …

Regulation of bacterial iron homeostasis is often controlled by the iron-sensing ferric uptake
repressor (Fur). The Bacillus subtilis Fur protein acts as an iron-dependent repressor for …

Microorganisms in most ecological niches are constantly exposed to variations of many
environmental factors, including temperature; oxygen, nutrient, and water availability; …

Background Rhizobium tropici CIAT 899 and Rhizobium sp. PRF 81 are α-Proteobacteria
that establish nitrogen-fixing symbioses with a range of legume hosts. These strains are …

Abstract Iron–sulfur (Fe–S) cluster containing proteins that regulate gene expression are
present in most organisms. The innate chemistry of their Fe–S cofactors makes these …
