The role of Fe–S proteins in sensing and regulation in bacteria

Current Opinion in Microbiology, 2003
Fe-S clusters are key to the sensing and transcription functions of three transcription factors, FNR, IscR and SoxR. All three proteins were discovered in Escherichia coli but experimental data and bioinformatic predictions suggest that homologs of these proteins exist in other bacterial species, highlighting the widespread nature of Fe-S-dependent ...

Evidence for one-electron transfer by the Fe protein of nitrogenase

Biochemical and Biophysical Research Communications, 1978
Abstract The number of electrons transferred per molecule of the Fe protein of nitrogenase from Clostridium pasteurianum was determined. The Fe protein was enzymically oxidized in the presence of MgATP and a small amount of MoFe protein, and dithionite was introduced to reduce part of the Fe protein.

Directed Cleavage of RNA with Protein-Tethered EDTA–Fe

Methods, 1999
There are several methods for locating the RNA site where a protein binds. One of the less common methods is directed cleavage of the RNA by an EDTA-Fe reagent tethered to the protein. The reaction of the EDTA-Fe(III) with ascorbate or hydrogen peroxide produces reactive oxygen species, such as hydroxyl radicals, localized within a 10-A radius of the ...

On the path to [Fe-S] protein maturation: A personal perspective

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research
Azotobacter vinelandii is a genetically tractable Gram-negative proteobacterium able to fix nitrogen (N2) under aerobic growth conditions. This narrative describes how biochemical-genetic approaches using A. vinelandii to study nitrogen fixation led to the formulation of the "scaffold hypothesis" for the assembly of both simple and complex [Fe-S ...
