Abstract：
:The cDNA clone lambda ML-1 encoding one of the extracellular lignin peroxidases from the white rot fungus, Phanerochaete chrysosporium, was heterologously expressed in an active form using a recombinant baculovirus system. The glycosylated extracellular form of the recombinant protein contained the ferriprotoporphyrin IX moiety and was capable of oxidizing both iodide and the model lignin compound, veratryl alcohol. In comparative peroxidase assays using guaiacol and Mn(II), the recombinant lignin peroxidase did not appear to be Mn(II) dependent. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis demonstrated that the heterologously expressed peroxidase had an apparent molecular weight similar to that of the native fungal isozyme H8. The elution profile of the active recombinant enzyme derived by ion-exchange chromatography and immunoblot analysis using an anti-H8 monoclonal antibody provided further evidence that the lambda ML-1 DNA encodes the lignin peroxidase H8.
