Abstract

The mechanism by which iron-storage proteins take up and oxidise iron(II) is not understood. We show by rapid-kinetic and EPR measurements that iron uptake, in vitro, by a bacterial iron-storage protein, bacterioferritin, involves at least three kinetically distinguishable phases: phase 1, the binding of Fe(II) ions, probably at a dimeric iron ferroxidase centre; phase 2, oxidation of the Fe(II) dimer and production of mononuclear Fe(III); and phase 3, iron core formation.
