Endonuclease III is an iron-sulfur protein
Biochemistry, 1989Elemental analyses, Mössbauer, and EPR data are reported to show that endonuclease III of Escherichia coli is an iron-sulfur protein. Mössbauer spectra of protein freshly prepared from E. coli grown on 57Fe-enriched medium demonstrate that the native enzyme contains a single 4Fe-4S cluster in the 2+ oxidation state, with a net spin of zero.

Publisher Summary This chapter discusses iron-sulfur proteins. Iron proteins are divided into three groups. If the iron atom is coordinated to a porphyrin, the protein is called a “hemoprotein,” irrespective of the chemistry of the axial ligands. If the iron is coordinated to sulfur from either cysteine or from inorganic sulfur, then the protein is ...

Electrochemistry of iron-sulfur proteins
1997Iron-sulfur proteins and enzymes are unique because they possess one or more iron-sulfur clusters. They are ubiquitous in nature, playing key roles in photosynthesis, nitrogen fixation, and terminal respiration, not to mention a host of other biologically important reactions including CO oxidation to CO2, interconversion of H2 and H+, and sulfite ...

EPR Spectroscopy of Iron—Sulfur Proteins
1992Publisher Summary This chapter describes electron paramagnetic resonance (EPR) spectroscopy of iron–sulfur proteins. The first EPR experiments on biological systems were carried out along the same lines. Many spectra were taken as a function of the orientation of the magnetic field with respect to the axes of the hemoglobin crystals frozen in their ...
