ORGANIC HYDROPEROXIDE RESISTANCE PROTEIN FROM DEINOCOCCUS RADIODURANS


Overview

The three-dimensional structure of the organic hydroperoxide resistance protein (OHRP) from Deinococcus radiodurans as determined using single crystal xray diffraction techniques is reported. Comparison of the structure with that obtained for OHRP from Pseudomonas aeruginosa reveals that the polypeptide chain of OHRPs can adopt two significantly different conformations ("in" and "out") in the region of the active site disulfide moiety. It is postulated that the closed configuration is consistent with efficient catalysis of the reduction of organic hydroperoxides, whereas the open form is required for enzyme recycling. Comparison of the structures of OHRP and that of the osmotically induced protein C (OsmC) from Mycoplasma pneumoniae shows that OHRPs and OsmCs are structurally homologous, perhaps indicating related functions for the two families of proteins.
