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|PIRNR:PIRNR002560}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=4 Fe(2+) + 4 H(+) + O2 = 4 Fe(3+) + 2 H2O;
CC Xref=Rhea:RHEA:11148, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:15379, ChEBI:CHEBI:29033, ChEBI:CHEBI:29034; EC=1.16.3.1;
CC Evidence={ECO:0000256|PIRNR:PIRNR002560};
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 -!- SIMILARITY: Belongs to the bacterioferritin family.
CC {ECO:0000256|ARBA:ARBA00008093, ECO:0000256|PIRNR:PIRNR002560,
CC ECO:0000256|RuleBase:RU000623}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
