Mn(II) Regulation of Lignin Peroxidases and Manganese-Dependent Peroxidases from Lignin-Degrading White Rot Fungi.
Two families of peroxidases-lignin peroxidase (LiP) and manganese-dependent lignin peroxidase (MnP)-are formed by the lignin-degrading white rot basidiomycete Phanerochaete chrysosporium and other white rot fungi. Isoenzymes of these enzyme families carry out reactions important to the biodegradation of lignin. This research investigated the regulation of LiP and MnP production by Mn(II). In li...
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 کاملKinetic mechanism of pyranose 2-oxidase from trametes multicolor.
Pyranose 2-oxidase (P2O) from Trametes multicolor is a flavoprotein oxidase that catalyzes the oxidation of aldopyranoses by molecular oxygen to yield the corresponding 2-keto-aldoses and hydrogen peroxide. P2O is the first enzyme in the class of flavoprotein oxidases, for which a C4a-hydroperoxy-flavin adenine dinucleotide (FAD) intermediate has been detected during the oxidative half-reaction...
متن کاملLignin-degrading peroxidases from the genome of the selective ligninolytic fungus Ceriporiopsis subvermispora*
Background: The first genome of a selective lignin-degrader is available. Results: Its screening shows 26 peroxidase genes, and five were heterologously expressed and catalytic properties investigated. Conclusion: Two new peroxidases oxidize simple and dimeric lignin models and efficiently depolymerize lignin. Significance: Although lignin peroxidase and versatile peroxidase had not been report...
متن کاملRedox Catalysis Facilitates Lignin Depolymerization
Lignin is a recalcitrant and underexploited natural feedstock for aromatic commodity chemicals, and its degradation generally requires the use of high temperatures and harsh reaction conditions. Herein we present an ambient temperature one-pot process for the controlled oxidation and depolymerization of this potent resource. Harnessing the potential of electrocatalytic oxidation in conjugation ...
