Induction of Laccase, Lignin Peroxidase and Manganese Peroxidase Activities in White-Rot Fungi Using Copper Complexes

Manganese regulation of veratryl alcohol in white rot fungi and its indirect effect on lignin peroxidase.

Many white rot fungi are able to produce de novo veratryl alcohol, which is known to be a cofactor involved in the degradation of lignin, lignin model compounds, and xenobiotic pollutants by lignin peroxidase (LiP). In this study, Mn nutrition was shown to strongly influence the endogenous veratryl alcohol levels in the culture fluids of N-deregulated and N-regulated white rot fungi Bjerkandera...

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...

Comparison of lignin peroxidase, horseradish peroxidase and laccase in the oxidation of methoxybenzenes.

Lignin peroxidase oxidizes non-phenolic substrates by one electron to give aryl-cation-radical intermediates, which react further to give a variety of products. The present study investigated the possibility that other peroxidative and oxidative enzymes known to catalyse one-electron oxidations may also oxidize non-phenolics to cation-radical intermediates and that this ability is related to th...
