In silico definition of new ligninolytic peroxidase sub-classes in fungi and putative relation to fungal life style.

ABSTRACT: Ligninolytic peroxidases are microbial enzymes involved in depolymerisation of lignin, a plant cell wall polymer found in land plants. Among fungi, only Dikarya were found to degrade lignin. The increase of available fungal genomes allows performing an expert annotation of lignin-degrading peroxidase encoding sequences with a particular focus on Class II peroxidases (CII Prx). In addition to the previously described LiP, MnP and VP classes, based on sequence similarity, six new sub-classes have been defined: three found in plant pathogen ascomycetes and three in basidiomycetes. The presence of CII Prxs could be related to fungal life style. Typically, necrotrophic or hemibiotrophic fungi, either ascomycetes or basidiomycetes, possess CII Prxs while symbiotic, endophytic or biotrophic fungi
