Iron-bound crystal structure of Dps-like peroxide resistance protein (Dpr) from Streptococcus suis.Iron-bound crystal structure of Dps-like peroxide resistance protein (Dpr) from Streptococcus suis.
Structural highlights
2bw1 is a 12 chain structure with sequence from Streptococcus suis. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
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.
