[[http://www.uniprot.org/uniprot/BFR_ECOLI BFR_ECOLI]] 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 mineralized iron core can contain as many as 2700 iron atoms/24-meric molecule.<ref>PMID:10769150</ref> <ref>PMID:14636073</ref>
