Legumes, which develop a symbiosis with nitrogen-fixing bacteria, have an increased
demand for iron. Iron is required for the synthesis of iron-containing proteins in the host …

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 …

Bacillus subtilis was reported to produce the catecholic siderophore itoic acid (2, 3-
dihydroxybenzoate (DHB)-glycine) in response to iron deprivation. However, by inspecting …

Despite the usually high abundance of iron (Fe) in soils, the low solubility of Fe-bearing
minerals restricts the available Fe pools in most aerobic soils to levels that are far below …

▪ 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 …

The ability of bacteria to develop resistance to antimicrobial agents poses problems in the
treatment of numerous bacterial infections. One method to circumvent permeability-mediated …

The outer membrane permeability barrier is an important resistance factor of bacterial
pathogens. In combination with drug inactivating enzymes, target alteration and efflux, it can …

We describe a novel diverse family of metal ion transporter (CDF) proteins (the cation
diffusion facilitator (CDF) family) with members occurring in both prokaryotes and …

We present the cloning and characterization of an Arabidopsis gene, FRD3, involved in iron
homeostasis. Plants carrying any of the three alleles of frd3 constitutively express three …

Members of the SLC11 (NRAMP) family transport iron and other transition-metal ions across
cellular membranes. These membrane proteins are present in all kingdoms of life with a …
