Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

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.By similarity

Catalytic activityi

4 Fe2+ + 4 H+ + O2 = 4 Fe3+ + 2 H2O.

Cofactori

Protein has several cofactor binding sites:
  • heme bBy similarityNote: Binds 1 heme b (iron(II)-protoporphyrin IX) group per dimer.By similarity
  • Fe cationBy similarityNote: Binds 2 iron ions per subunit. The catalytic dinuclear iron-binding site within each subunit is known as the ferroxidase center.By similarity
