    Peroxidases catalyze a wide variety of peroxide-dependent oxidations. Based on sequence alignments, heme peroxidases have been divided into three classes. Crystal structures are available for peroxidases of classes I and II, but until now no structure has been determined for class III, the classical extracellular plant peroxidases.
