As the iron core isprogressively laid down, the mechanism
of iron oxidation changes from a protein dominated
process with H202 being the primary product of
O2 reduction to a mineral surface dominated process
where H20 is the primary product. These results emphasize
the importance of the apoferritin shell in facilitating
iron oxidation in the early stage of iron deposition
prior to significant development of the polynuclear
iron core.
