General annotation (Comments)

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 By similarity.

Catalytic activity

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

Cofactor

Binds 1 heme B (iron-protoporphyrin IX) group per dimer By similarity.

Binds 2 iron ions per subunit. The catalytic dinuclear iron-binding site within each subunit is known as the ferroxidase center By similarity.

Subunit structure

Homooligomer of 24 subunits, arranged as 12 dimers, that are packed together to form an approximately spherical molecule with a central cavity, in which large amounts of iron can be deposited By similarity.

Sequence similarities

Belongs to the bacterioferritin family.

Contains 1 ferritin-like diiron domain.
