Abstract
The Ohr / OsmC is a super-family of proteins consists of three sub-groups: Ohr; OsmC and Ohr-like. Ohr ("Organic Hydroperoxide Resistance proteins") are thiol-dependent peroxidases that efficiently reduce organic hydroperoxides, but not H2O2. These proteins are primarily found in bacteria and also in other microbial eukaryotes, while absent in vertebrates and vascular plants, making them …
