-
a dimeric lignin model compound, derivatization with tetramethylsilane is carried out to analyze guaiacyl glycerol-beta-guaiacyl ether, GGE. The catalytic promiscuity of tyrosinase seemed to cleave the Calpha-Cbeta bond in GGE, yielding vanillin and possibly an unstable o-(2-hydroxyethyl)guaiacol radical. The unstable o-(2-hydroxyethyl)guaiacol radical might be further catalyzed to guaiacol and 2-hydroxyacetaldehyde by the tyrosinase, and then guaiacol might be polymerized to an unidentified product

catalytic activity of lignin peroxidase and partition of veratryl alcohol in sodium bis(2-ethylhexyl)sulfosuccinate /isooctane/toluene/water reverse micelles. Activity depends to a great extent, on the composition of the reverse micelles. Optimum activity occurs at a molar ratio of water to sodium bis(2-ethylhexyl)sulfosuccinate of 11, pH 3.6, and a volume ratio of isooctane to toluene of 79. Under optimum conditions, the half-life of LiP is circa 12 h

LiP uses H2O2 to catalyze one-electron oxidation of chemicals to free radicals. Hydrogen peroxide oxidizes the heme-LiP by two electrons to LiP I, a ferryl (Fe(IV)) n-porphyrin cation radical of LiP. A substrate molecule can then be oxidized by one electron to a radical, and LiP I is reduced by one electron to LiP II. A subsequent oxidation of another substrate molecule by LiP II returns the LiP to its ferric resting state. The presence of excess H2O2 or slow reduction of LiP II to resting state may lead to the oxidation of LiP II to LiP III, an inactivated enzyme form. This is called LiP cycle. Optimization of enzyme activity measurement and assay condition, overview. The optimum combination of parameters for the maximum is as follows, including pretreatment temperature of 120°C, pretreatment time of 5 min, reaction temperature of 30°C, enzyme amount of 3.75 U/100 ml, 50 mM sodium lactate-hydrochloric acid buffer of pH 1.5, H2O2 concentration of 20 mM and H2O2 amount of 1 ml

bioelectric oxidation of organic substrates by LiP immobilized on graphite electrodes: the enzyme can establish direct (i.e. mediatorless) electronic contact with graphite electrodes. In the case of the so called direct electron transfer reaction, the oxidized enzyme is directly reduced by the electrode to the initial ferriperoxidase state. In the presence of an electron donor other than electrode, the two-electron reduction of enzyme form E1 (containing an oxyferryl iron and a porphyrin pi cation radical) to the initial ferriperoxidase occurs through the intermediate formation of enzyme form II by a sequential one-electron transfer from the electron donor. The formed oxidized electron donor is then electrochemically reduced by the electrode. Different mechanisms for the bioelectrocatalysis of the enzyme depend on the chemical nature of the mediators and are of a special interest both for fundamental science and for application of the enzyme as solid-phase bio(electro)catalyst for decomposition/detection of of recalcitrant aromatic compounds

catalysis of degradation of the dimer to products by an acid-stabilized variant of lignin peroxidase isozyme H8 increases from 38.4% at pH 5.0 to 92.5% at pH 2.6. At pH 2.6, the observed product distribution results from 65.5% beta-O-4' ether bond cleavage, 27.0% Calpha-C1 carbon bond cleavage, and 3.6% Calpha-oxidation as by-product. Enzyme LiPH8 catalyzes the oxidative cleavage of both beta-O-4' ether and C-C bonds in aryl ether dimers and catalyzes breaking of beta-O-4' ether, C-C, and C-H bonds in trimeric lignin model compounds. The distribution of products is pH-dependent. Study catalysis of bond cleavage events in a phenolic lignin dimer by quantitative analysis of product formation during LiPH8-catalyzed degradation of a GGE model compound (GGE-NIMS compound) using nanostructure-initiator mass spectrometry. Low pH conditions drive reaction equilibrium toward the favorable formation of the active cationic radical intermediate. The cationic radical intermediate formed from LiPH8/H2O2-catalyzed 1-electron oxidation of GGE dimer is capable of undergoing a variety of reactions such as side-chain oxidation, C-C bond, and beta-O-4' ether bond cleavage. The intermediates are predicted from a heterolytic bond cleavage reaction mechanism when the first step 1-electron oxidation takes place at lower redox potential-Ring A. The deprotonation of the short-lived cationic radical results in the formation of the phenoxy radical which sequentially cleaved into fragments. Protonation of hydroxyl group under acidic conditions is a key step in bond-cleavage pathways

lignin peroxidase is an extracellular hemeprotein that is H2O2-dependent, with an unusually high redox potential and low optimum pH. It is capable of oxidizing a variety of reducing substrates, including polymeric substrates. It has the distinction of being able to oxidize methoxylated aromatic rings without a free phenolic group, which generates cation radicals that can react further by a variety of pathways, including ring opening, demethylation, and phenol dimerization. In contrast with laccases, LiP does not require mediators to degrade high redox-potential compounds, but it needs H2O2 to initiate catalysis. Substrate specificity, no or poor activity with ferulic acid, vanillic acid, diaminobenzidine, and HoBT. Purified LiP obtained from immobilized Phanerochaete chrysosporium completely decolorizes bromophenyl blue, bromothymol blue, and bromocresol green, purified enzyme from immobilized Phanerochaete chrysosporium shows increased dye decolorization efficiency compared to the enzyme from non-immobilized Phanerochaete chrysosporium

the fungal lignin peroxidase does not produce the veratryl alcohol cation radical as a diffusible ligninolytic oxidant. Reaction-diffusion model and solution-phase model, overview. The oxidation of veratryl alcohol (VA) by the enzyme in air at physiological pH 4.5 consumes O2 and produces about 1.1 veratraldehyde per H2O2 supplied. This finding suggests that some VAx02cation radical may escape oxidation at the enzyme's active site, hydrolyzing instead to give benzylic radicals that rapidly add O2. The resulting alpha-hydroxyperoxyl radicals would in turn eliminate the H2O2 precursor HO2 radical, thus accounting for the enhancement in veratraldehyde yield. VA is required for the enzyme to oxidize 4-methoxymandelic acid, which quenches the ESR signal of the VA produced, and veratraldehyde production during these reactions occurs only after all of the 4-methoxymandelic acid has been consumed. Moreover, the rate of 4-methoxymandelic acid oxidation by the enzyme exhibits saturation kinetics as the concentration of VA is increased. Enzymatic oxidations of dye-functionalized beads

The recombinant mutant enzyme Rh_DypB shows a classical peroxidase activity which is significantly increased by adding Mn2+ ions, kinetic parameters for H2O2, Mn2+, ABTS, and 2,6-DMP are determined. The enzyme shows broad dye-decolorization activity, especially in the presence of Mn2+, oxidizes various aromatic monomers from lignin, and cleaves the guaiacylglycerol-beta-guaiacyl ether (GGE), i.e., the Calpha-Cbeta bond of the dimeric lignin model molecule of beta-O-4 linkages. Under optimized conditions, 2 mM GGE is fully cleaved by recombinant Rh_DypB, generating guaiacol in only 10 min, at a rate of 12.5 micromol/min/mg enzyme.
