摘要：

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