Abstract: Two heme proteins, manganese peroxidase (MnP) and lignin peroxidase (LiP), play key roles in the fungal depolymeri-zation of lignin. Many cDNA and genomic clones encoding these peroxidases have been published. We report here on the cDNA AMP-2 encoding the MnP isozyme H3 from Phanerochaete chrysosporium strain BKM-F-1767. We also demonstrate that the MnP-encoding gene, AMP-1, encoding isozyme H4, and AMP-2 reside on separate chromosomes from each other and from the LiP-encoding genes. From these results, it is apparent that AMP-2 is not linked to AMP-I or other genes believed to be involved in lignin depolymerization, such as the LiP and glyoxal oxidase.

Keywords: cDNA, Phanerochaete chrysosporium, Genomic organization, Lignin, Maganese peroxidase-encoding genes.
