[https://www.uniprot.org/uniprot/BFR_DESDA BFR_DESDA] Iron-storage protein, whose ferroxidase center binds Fe(2+) ions, oxidizes them by dioxygen to Fe(3+), and participates in the subsequent Fe(3+) oxide mineral core formation within the central cavity of the protein complex.

The first crystal structure of a native di-iron center in an iron-storage protein (bacterio)ferritin is reported. The protein, isolated from the anaerobic bacterium Desulfovibrio desulfuricans, has the unique property of having Fe-coproporphyrin III as its heme cofactor. The three-dimensional structure of this bacterioferritin was determined in three distinct catalytic/redox states by X-ray crystallography (at 1.95, 2.05 and 2.35 A resolution), corresponding to different intermediates of the di-iron ferroxidase site. Conformational changes associated with these intermediates support the idea of a route for iron entry into the protein shell through a pore that passes through the di-iron center. Molecular surface and electrostatic potential calculations also suggest the presence of another ion channel, distant from the channels at the three- and four-fold axes proposed as points of entry for the iron atoms.
