The organic hydroperoxide resistance protein, thiol-dependent peroxidase that is a central player in response to stress induced by organic hydroperoxides in bacteria. It has unique three-dimensional structure and requires dithiols to support its activity. It forms an oval-shaped, tight homodimer and have two active site positioned on the opposite faces of the dimer. We have determined series of the structure of OHR-like protein from V. cholera and were able to reveal the enzymes structure in the reduce state (3I07), in the presence of captopril molecule (3LUS). FOX assays confirmed that it metabolizes hydrogen peroxide.
