Function
function
Iron-storage protein, whose ferroxidase center binds Fe2+ ions, oxidizes them by dioxygen to Fe3+, and participates in the subsequent Fe3+ oxide mineral core formation within the central cavity of the protein complex.
Catalytic activity
- 4 Fe2+ + 4 H+ + O2 = 4 Fe3+ + 2 H2O
Cofactor
Protein has several cofactor binding sites:
