Iron is an essential nutrient for nearly all organisms but presents problems of toxicity, poor
solubility and low availability. These problems are alleviated through the use of iron-storage …

▪ Abstract This review summarizes current knowledge about genes whose products function
in the transport of various cationic macronutrients (K, Ca) and micronutrients (Cu, Fe, Mn …

Dissimilatory iron-reducing bacteria (DIRB) couple the oxidation of organic matter or H2 to
the reduction of iron oxides. The factors controlling the rate and extent of these reduction …

FhuA, the receptor for ferrichrome-iron in Escherichia coli, is a member of a family of integral
outer membrane proteins, which, together with the energy-transducing protein TonB …

A colony morphology type is described in which cells of Salmonella typhimurium form a rigid
multicellular network with expression of thin aggregative fimbriae that mediate tight …

FhuA protein facilitates ligand-gated transport of ferrichrome-bound iron across Escherichia
coli outer membranes. X-ray analysis at 2.7 Å resolution reveals two distinct conformations …

Fur (ferric uptake regulator) proteins control iron uptake in many Gram‐negative bacteria.
Although Fur homologues have been identified in Gram‐positive bacteria, their roles in gene …

Cells growing in aerobic environments have developed intricate strategies to overcome the
scarcity of iron, an essential nutrient. In Gram‐negative bacteria, high‐affinity iron acquisition …

Several novel but similar heavy metal ion transporters, Zrt1, Zrt2, Zip1-4 and Irt1, have
recently been characterized. Zrt1, Zrt2 and Zip1-4 are probably zinc transporters in …

Background: Virulence in the pathogenic bacterium Yersinia pestis, causative agent of
bubonic plague, has been correlated with the biosynthesis and transport of an iron-chelating …
