To maintain iron homeostasis within the cell, bacteria have evolved various types of iron
acquisition systems. Ferric iron (Fe3+) is the dominant species in an oxygenated …

Virtually all organisms require iron and have evolved to obtain this element in free or
chelated forms. Under anaerobic or low pH conditions commonly encountered by numerous …

Bacteria commonly utilise a unique type of transporter, called Feo, to specifically acquire the
ferrous (Fe 2+) form of iron from their environment. Enterobacterial Feo systems are …

The ferrous iron transport system Feo is widely distributed among bacterial species, yet its
physical structure and mechanism of iron transport are poorly understood. In Vibrio …

Bacteria are confronted with a low availability of iron owing to its insolubility in the Fe3+ form
or its being bound to host proteins. The bacteria cope with the iron deficiency by using host …

Bacteria require iron for growth, with only a few reported exceptions. In many environments,
iron is a limiting nutrient for growth and high affinity uptake systems play a central role in iron …

The cytoplasmic membrane protein FeoB of Escherichia coli, Helicobacter pylori, Legionella
pneumophila and Synechocystis sp. strain PCC 6803 is necessary for Fe 2+ uptake. The C …

Iron is essential to virtually all organisms, but poses problems of toxicity and poor solubility.
Bacteria have evolved various mechanisms to counter the problems imposed by their iron …

Most of the iron in a mammalian body is complexed with various proteins. Moreover, in
response to infection, iron availability is reduced in both extracellular and intracellular …

In many bacterial feo loci, the feoA gene is associated with the feoB gene. While the feoB-
encoded FeoB protein has been demonstrated as a ferrous iron [Fe (II)] transporter, the …
