Molecular Mechanism of Ferricsiderophore Transport via the Outer Membrane Receptor FhuA in <em>Escherichia coli</em>.
… receptors. The FhuA receptor protein transports ferrichrome, a siderophore produced by <em>Ustilago sphaerogena</em>. We determined the binding affinity of variants from the conserved 'lock region' of FhuA and also created and characterized variants of the highly conserved R452 to determine its …

Haem and xenosiderophore mediated iron acquisition by sinorhizobium meliloti and pseudomonas aeruginosa
… FhuA1 and FhuA2 function in the utilisation of ferrichrome and ferrioxamine B respectively. Analysis of the region directly downstream of FhuA2 resulted in the identification of a ferrioxamine B specific ferric iron reductase, fhuF (smc01658), and a periplasmic siderophore binding protein, fhuP …

Biochemical characterization of Aspergillus fumigatus SidA: a flavin-dependent N-hydroxylating enzyme
Ferrichrome is a hydroxamate-containing siderophore produced by the pathogenic fungus Aspergillus fumigatus during infection. This siderophore includes N5-hydroxylated L-ornithine in the peptide backbone that serve as iron chelators. Af SidA is the L-ornithine N5-hydroxylase, which performs the …

Characterization of FhuA 104/149C: a Double Cysteine FhuA Mutant with Normal Binding and Diminished Transport
… severely reduced transport of radio-labeled ferrichrome. In the course of this study, this protein was HPLC purified for structural studies by crystallization and X-ray diffraction. In addition, protein interaction studies were performed with purified TonB-C terminal revealing no impact of …
