CRYSTAL STRUCTURE OF DPS-LIKE PEROXIDE RESISTANCE PROTEIN (DPR) FROM STREPTOCOCCUS SUIS
Overview
The Dps-like peroxide resistance protein (Dpr) is an aerotolerance and, hydrogen peroxide resistance agent found in the meningitis-associated, pathogen Streptococcus suis. Dpr is believed to act by binding free, intracellular iron to prevent Fenton chemistry-catalysed formation of, toxic hydroxyl radicals. The crystal structure of Dpr has been determined, to 1.95 A resolution. The final model has an Rcyst value of 18.5% (Rfree =, 22.4%) and consists of 12 identical monomers (each of them comprising a, four alpha-helix bundle) that form a hollow sphere obeying 23 symmetry., Structural features show that Dpr belongs to the Dps family of bacterial, proteins. Twelve putative ferroxidase centers, each formed at the, interface of neighboring monomer pairs, were identified in the Dpr, structure ... [(full description)]
