Significance: Iron is required for growth and is often redox active under cytosolic conditions.
As a result of its facile redox chemistry, iron homeostasis is intricately involved with oxidative …

Bacteria respond dynamically to the changes in zinc availability. Repression by the Bacillus
subtilis transcription factor Zur requires Zn (II), which binds with negative cooperativity to two …

Maintaining iron homeostasis is a necessity for all living organisms, as free iron augments
the generation of reactive oxygen species like superoxide anions, at the risk of subsequent …

The soft rot Erwinia are members of the most studied bacterial family, the
Enterobacteriaceae, which also includes other important plant and animal pathogens such …

Proteome analysis of Bacillus subtilis cells grown at low and high salinity revealed the
induction of 16 protein spots and the repression of 2 protein spots, respectively. Most of …

Iron is an essential nutrient for most bacteria. Depending on the oxygen available in the
surrounding environment, iron is found in two distinct forms: ferrous (Fe II) or ferric (Fe III) …

The biosynthetic gene cluster of the myxochelin‐type iron chelator was cloned from
Stigmatella aurantiaca Sg a15 and characterized. This catecholate siderophore was only …

In response to low iron availability, Vibrio parahaemolyticus synthesizes and secretes a
polyhydroxycarboxylate-type siderophore vibrioferrin which is composed of 1 mol each of 2 …

The only known niche of the human pathogen Helicobacter pylori is the gastric mucosa,
where large fluctuations of pH occur, indicating that the bacterial response and resistance to …

Iron is essential for all bacteria. In most bacteria, intracellular iron homeostasis is tightly
regulated by the ferric uptake regulator Fur. However, how Fur activates the iron-uptake …
