Function
DPS_STRSU Protects DNA from oxidative damage by sequestering intracellular Fe(2+) ion and storing it in the form of Fe(3+) oxyhydroxide mineral. One hydrogen peroxide oxidizes two Fe(2+) ions, which prevents hydroxyl radical production by the Fenton reaction (By similarity). It binds and incorporates Fe(2+) iron. Is responsible for hydrogen peroxide resistance. Does not bind DNA.
