CRYSTAL STRUCTURE OF THE ORGANIC HYDROPEROXIDE RESISTANCE PROTEIN OHRB OF BACILLUS SUBTILIS

Overview

The crystal structure of the fully oxidized form of the Bacillus subtilis, organic hydroperoxide-resistance (OhrB) protein is reported at 2.1 A, resolution. The electron density reveals an intact catalytic disulfide, bond (Cys55-Cys119) in each of the two molecules, which are intertwined, into a canonical obligate dimer. However, the stereochemistry of the, disulfides is unorthodox and strained, suggesting that they are sensitive, to reducing agents. A deep solvent-accessible gorge reaching Cys55 may, represent the access route for the reductant.
