Two heme proteins, manganese peroxidase (MnP) and lignin peroxidase (L
iP), play key roles in the fungal depolymerization of lignin. Many cDN
A and genomic clones encoding these peroxidases have been published. W
e report here on the cDNA lambda MP-2 encoding the MnP isozyme H3 from
Phanerochaete chrysosporium strain BKM-F-1767. We also demonstrate th
at 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 l
ignin depolymerization, such as the LiP and glyoxal oxidase.
