Mössbauer Effect Studies on the Four-iron Centres of Two Iron-sulphur Proteins
Year: 1974
Type: article
Abstract: 57Fe Mössbauer effect studies have been carried out on the ferredoxin from Clostridium pasteurianum and on the high potential iron-sulphur protein (HiPIP) from Chromatium to investigate the 4 Fe-4 S centres found in these proteins. A consideration of the chemical shifts in the different redox states of the proteins enables a characterization of the iron atoms in terms of formal valences. The observed magnetic hyperfine fields give evidence for anti-ferromagnetic coupling of the iron atoms within each centre. The Mössbauer spectroscopy data is used to justify a model for the iron atoms in the centre.
