CC -!- FUNCTION: Iron-storage protein, whose ferroxidase center binds Fe(2+)
CC ions, oxidizes them by dioxygen to Fe(3+), and participates in the
CC subsequent Fe(3+) oxide mineral core formation within the central
CC cavity of the protein complex. {ECO:0000256|ARBA:ARBA00037326}.
CC -!- COFACTOR:
CC Name=Fe cation; Xref=ChEBI:CHEBI:24875;
CC Evidence={ECO:0000256|ARBA:ARBA00001962};
CC -!- COFACTOR:
CC Name=heme b; Xref=ChEBI:CHEBI:60344;
CC Evidence={ECO:0000256|ARBA:ARBA00001970};
CC -!- SUBUNIT: Oligomer of 24 subunits, arranged as 12 dimers, that are
CC packed together to form an approximately spherical molecule with a
CC central cavity, in which large amounts of iron can be deposited.
CC {ECO:0000256|ARBA:ARBA00011713}.
CC -!- SIMILARITY: Belongs to the bacterioferritin family.
CC {ECO:0000256|ARBA:ARBA00008093}.
