Abstract
Mossbauer spectroscopy has been used to study Fe(III)-apoferritin complexes, formed after the addition of Fe(II) to apoferritin in air. The spectra showed the presence of divalent, dimeric trivalent and small clusters of trivalent iron. The amount of divalent and dimeric iron and the average iron-iron distance in the small clusters, diminished with time. The dynamic behaviour of iron in iron poor ferritin crystals, indicating that the iron is bound differently in the two systems and showing the role of different kinds of water in ferritin on protein dynamics.
