Isoenzyme multiplicity and characterization of recombinant manganese peroxidases from Ceriporiopsis subvermispora and Phanerochaete chrysosporium.
We expressed cDNAs coding for manganese peroxidases (MnPs) from the basidiomycetes Ceriporiopsis subvermispora (MnP1) and Phanerochaete chrysosporium (H4) under control of the alpha-amylase promoter from Aspergillus oryzae in Aspergillus nidulans. The recombinant proteins (rMnP1 and rH4) were expressed at similar levels and had molecular masses, both before and after deglycosylation, that were ...
متن کاملComparative genomics of Ceriporiopsis subvermispora and Phanerochaete chrysosporium provide insight into selective ligninolysis.
Efficient lignin depolymerization is unique to the wood decay basidiomycetes, collectively referred to as white rot fungi. Phanerochaete chrysosporium simultaneously degrades lignin and cellulose, whereas the closely related species, Ceriporiopsis subvermispora, also depolymerizes lignin but may do so with relatively little cellulose degradation. To investigate the basis for selective ligninoly...
متن کاملExpression of phanerochaete chrysosporium genes encoding lignin peroxidases, manganese peroxidases, and glyoxal oxidase in wood
Expression of Phanerochaete chrysosporium genes encoding ligninolytic enzymes was assessed in wood. Poly(A) RNA was extracted from colonized wood chips by magnetic capture, and specific transcripts were quantified by competitive reverse transcriptase PCR. mRNA levels varied substantially among lignin peroxidase genes, and transcript patterns were dramatically different from those in previous st...
متن کاملHomologous expression of recombinant manganese peroxidase in Phanerochaete chrysosporium.
The promoter region of the glyceraldehyde-3-phosphate dehydrogenase gene (gpd) was used to drive expression of mnp1, the gene encoding Mn peroxidase isozyme 1, in primary metabolic cultures of Phanerochaete chrysosporium. A 1,100-bp fragment of the P. chrysosporium gpd promoter region was fused upstream of the mnp1 gene to construct plasmid pAGM1, which contained the Schizophyllum commune ade5 ...
متن کاملManganese-dependent Peroxidase from Phanerochaete chrysosporium
A cDNA clone encoding a manganese-dependent peroxidase from the filamentous fungus Phanerochaete chrysosporium was isolated and characterized. The clone, AMP-1, was isolated by screening a X g t l l expression library with polyclonal antibodies raised against a purified manganese-dependent peroxidase (isozyme H4, PI 4.5). The XMP-1 cDNA sequence predicts a mature protein containing 358 amino a...
