Dye-decolorizing (DyP-type) peroxidases were first discovered in fungi and are named after their ability to degrade a wide range of dyes. Subsequently, additional members were found in the proteomes of other fungi, as well as in several bacteria. This shows that these enzymes are widespread like other peroxidases. Interestingly, recent genome sequence analysis shows that these enzymes are prominent in bacteria, whereas only a small number is found in fungi and higher eukaryotes. Their occurrence in archaea is even more limited. The most comprehensive overview of the DyP-type peroxidase superfamily is offered by the Interpro database. According to this database, the DyP superfamily comprises currently almost 4000 members, of which 3707 are found in bacteria, 117 in eukaryotes and 11 in archea. The growing number of putative DyP-type peroxidases identified in the proteomes of bacteria, emphasizes our previous suggestion that this superfamily should be renamed into the superfamily of bacterial peroxidases.
