CC -!- FUNCTION: Protects DNA from oxidative damage by sequestering CC intracellular Fe(2+) ion and storing it in the form of Fe(3+) CC oxyhydroxide mineral. One hydrogen peroxide oxidizes two Fe(2+) CC ions, which prevents hydroxyl radical production by the Fenton CC Fe(2+) ion (By similarity). It is capable of binding and CC sequestering Fe(2+) ion. Does not bind DNA. CC -!- CATALYTIC ACTIVITY: 2 Fe(2+) + H(2)O(2) + 2 H(+) = 2 Fe(3+) + 2 CC H(2)O. CC -!- SUBUNIT: The 12 subunits form a hollow sphere into which the CC mineral iron core of up to 500 Fe(3+) can be deposited (By CC similarity). Homododecamer. CC -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity). CC -!- DOMAIN: 12 di-nuclear ferroxidase centers are located at the CC interfaces between subunits related by 2-fold symmetry axes. CC -!- SIMILARITY: Belongs to the dps family.
