DESCRIPTION

Also known as BFR_ECOLI, bfr. Iron-storage protein, whose ferroxidase center binds Fe(2+) ions, oxidizes them by dioxygen to Fe(3+), and participates in the subsequent Fe(3+) oxide mineral core formation within the central cavity of the protein complex. The mineralized iron core can contain as many as 2700 iron atoms/24-meric molecule. 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 as a ferric-oxy-hydroxide mineral core.
