Expression 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 کاملDirect interaction of lignin and lignin peroxidase from Phanerochaete chrysosporium.
Binding properties of lignin peroxidase (LiP) from the basidiomycete Phanerochaete chrysosporium against a synthetic lignin (dehydrogenated polymerizate, DHP) were studied with a resonant mirror biosensor. Among several ligninolytic enzymes, only LiP specifically binds to DHP. Kinetic analysis revealed that the binding was reversible, and that the dissociation equilibrium constant was 330 micro...
متن کاملInfluence of cellobiose oxidase on peroxidases from Phanerochaete chrysosporium.
Reduction of H2O2-oxidized manganese peroxidase (MnP), lignin peroxidase and, to some extent, horseradish peroxidase, was studied in the presence of cellobiose oxidase (CbO) and cellobiose. It was found that the reversion rates for MnP compound II and lignin peroxidase compound II back to native enzymes increased significantly in the presence of CbO and cellobiose. However, the reduction of cyt...
متن کاملPhysiology and molecular biology of the lignin peroxidases of Phanerochaete chrysosporium.
The white-rot basidiomycete Phanerochaete chrysosporium produces lignin peroxidases (LiPs), a family of extracellular glycosylated heme proteins, as major components of its lignin-degrading system. Up to 15 LiP isozymes, ranging in M(r) values from 38,000 to 43,000, are produced depending on culture conditions and strains employed. Manganese-dependent peroxidases (MnPs) are a second family of e...
متن کاملRole of manganese peroxidases and lignin peroxidases of Phanerochaete chrysosporium in the decolorization of kraft bleach plant effluent.
The role of lignin peroxidases (LIPs) and manganese peroxidases (MNPs) of Phanerochaete chrysosporium in decolorizing kraft bleach plant effluent (BPE) was investigated. Negligible BPE decolorization was exhibited by a per mutant, which lacks the ability to produce both the LIPs and the MNPs. Also, little decolorization was seen when the wild type was grown in high-nitrogen medium, in which the...
