SYSTEMATIC NAME

substrate:hydroperoxide oxidoreductase (RH-hydroxylating or epoxidising)
A heme protein with calcium binding motif (caleosin-type). Enzymes of this type include membrane-bound proteins found in seeds of different plants. They catalyse the direct transfer of one oxygen atom from an organic hydroperoxide, which is reduced into its corresponding alcohol to a substrate which will be oxidized. Reactions catalysed include hydroxylation, epoxidation and sulfoxidation. Preferred substrate and co-substrate are unsaturated fatty acids and fatty acid hydroperoxides, respectively. Plant seed peroxygenase is involved in the synthesis of cutin.
