Iron-sulfur repair YtfE protein from Escherichia coli: Structural characterization of the di-iron center
(Springer, 2008-06)
YtfE was recently shown to be a newly discovered protein required for the recovery of the activity of iron-sulfur-containing enzymes damaged by oxidative and nitrosative stress conditions. The Escherichia coli YtfE purified ...
Mitochondrial iron homeostasis and its dysfunctions in neurodegenerative disorders
(Elsevier, 2015)
Synthesis of the iron-containing prosthetic groups—heme and iron–sulfur clusters—occurs in mitochondria. The
mitochondrion is also an important producer of reactive oxygen species (ROS), which are derived fromelectrons
leaking ...
Glutathione Complexed Iron- Sulfur Centres. Reaction Intermediates and Evidence for a Template Effect Promoting Assembly and Stability
(Royal Society Of Chemistry, 2013-05)
Assembly and stabilization of a glutathione-complexed [2Fe–2S] cluster is promoted by aggregation of glutathione. The cluster core selects the tetramer species from a collection of equilibrating solution aggregate ...
Cytochromes c of Acidithiobacillus ferrooxidans
(FEMS Microbiol Lett. 2002 Apr 9;209(2):189-95, 2009)
Sulfur-hydrogen bond activation of thiols by the fragment CpFe(dppe)+: Cyclopentadienyl iron(III) thiolate complexes
(Elsevier Ltd, 1997)
Oxidative addition of thiols RSH, R = CH3, CH2CH2CH3, CH2C6H5, C(CH3)3 and C6H4Br, by the complex [CpFe(dppe)1] afforded the oxidized thiolate complexes [CpFe(dppe)-SR]PF6. The reaction of [CpFe(dppe)1] with HSC6H4NH2 ...
Effect of mitochondrial complex I inhibition on Fe-S cluster protein activity
(2011)
Iron-sulfur (Fe-S) clusters are small inorganic cofactors formed by tetrahedral coordination of iron atoms with sulfur groups. Present in numerous proteins, these clusters are involved in key biological processes such as ...
Biomining of iron-containing nanoparticles from coal tailings
(Springer Nature, 2019-07-10)
Sulfur minerals originating from coal mining represent an important environmental problem. Turning these wastes into value added by-products can be an interesting alternative. Biotransformation of coal tailings into ...
Models for ferredoxins: electronic structures of iron-sulfur clusters with one, two, and four iron atoms
(1985)
We report results of Xα valence bond scattered wave (Xα-VB-SW) calculations for a variety of clusters that mimic the active sites in iron-sulfur proteins: Fe(SR)41-,2- (R = H, CH3), Fe2S2(SH)42-,3-, and Fe4S4(SCH3)42-,3-. ...
Observation of stable 17 e iron(III) cyclopentadienyl radical complexes
(Sociedad Chilena de Quimica, 1999)
The EPR spectra of a series of mononuclear complexes [CpFe(dppe)SR]PF6 R = C6H5 (1), C3H7 (2), p-C6H4Br (3) and the binuclear [CpFe(dppe)-S-CH2CH2-S-CpFe(dppe)](PF6) 2 (4) were measured. All the paramagnetic complexes ...
