Identification of an iron–hepcidin complex [PDF]

open access: yes, 2008
Following its identification as a liver-expressed antimicrobial peptide, the hepcidin peptide was later shown to be a key player in iron homoeostasis. It is now proposed to be the 'iron hormone' which, by interacting with the iron transporter ferroportin,

Characterisation of the yeast Nfs1/Isd11 cysteine desulphurase complex [PDF]

open access: yes, 2010
PhDSmall inorganic assemblies of alternating ferrous/ferric iron and sulphide ions, so-called iron–sulphur (Fe–S) clusters, are probably nature‟s most ancient prosthetic groups.

The transcriptional repressor protein NsrR senses nitric oxide directly via a [2Fe-2S] cluster [PDF]

open access: yes, 2008
The regulatory protein NsrR, a member of the Rrf2 family of transcription repressors, is specifically dedicated to sensing nitric oxide ( NO) in a variety of pathogenic and non-pathogenic bacteria.

Physiological and Mechanistic Studies of Phototrophic Fe(II) Oxidation in Purple Non-sulfur Bacteria [PDF]

open access: yes, 2007
Phototrophic Fe(II)-oxidizing bacteria use electrons from ferrous iron [Fe(II)] and energy from light to drive reductive CO₂ fixation. This metabolism is thought to be ancient in origin, and plays an important role in environmental iron cycling. It has

Characterization of lacustrine iron sulfide particles with proton-induced X-ray emission. [PDF]

open access: yes, 1992
Black particles, collected by filtration (1.2~pm pore size) from the anoxic waters of a soft-water lake, were examined by a scanning proton microprobe which permitted quantitative elemental analysis by proton-induced X-ray emission (PIXE) and Rutherford ...

Structure-function relationships of the Mycobacterium tuberculosis transcription factor WhiB1.

open access: yesPLoS ONE, 2012
BackgroundMembers of the WhiB-like (Wbl) protein family possess iron-sulfur clusters and are implicated in the regulation of developmental processes in Actinomycetes. Mycobacterium tuberculosis possesses seven Wbl proteins.

Description of peptide bond planarity from high-resolution neutron crystallography

open access: yesBiophysics and Physicobiology, 2023
Neutron crystallography is a highly effective method for visualizing hydrogen atoms in proteins. In our recent study, we successfully determined the high-resolution (1.2 Å) neutron structure of high-potential iron-sulfur protein, refining the coordinates

Down the Iron Path: Mitochondrial Iron Homeostasis and Beyond

open access: yesCells, 2021
Cellular iron homeostasis and mitochondrial iron homeostasis are interdependent. Mitochondria must import iron to form iron–sulfur clusters and heme, and to incorporate these cofactors along with iron ions into mitochondrial proteins that support ...

Cluster and fold stability of E. coli ISC-type ferredoxin.

open access: yesPLoS ONE, 2013
Iron-sulfur clusters are essential protein prosthetic groups that provide their redox potential to several different metabolic pathways. Formation of iron-sulfur clusters is assisted by a specialised machine that comprises, among other proteins, a ...
