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 ECO:0000256|PIRNR:PIRNR002560}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=4 Fe(2+) + 4 H(+) + O2 = 4 Fe(3+) + 2 H2O;
