Abstract
Environmental problems resultant from organic pollutants are a major current challenge for modern societies. White rot fungi (WRF) are well known for their extensive organic compound degradation abilities. The unique oxidative and extracellular ligninolytic systems of WRF that exhibit low substrate specificity, enable them to display a considerable ability to transform or degrade different environmental contaminants. In recent decades, WRF and their ligninolytic enzymes have been widely applied in the removal of polycyclic aromatic hydrocarbons (PAHs), pharmaceutically active compounds (PhACs), endocrine disruptor compounds (EDCs), pesticides, synthetic dyes, and other environmental pollutants, wherein promising results have been achieved. This review focuses on advances in WRF-based bioremediation of organic pollutants over the last 10 years. We comprehensively document the application of WRF and their lignocellulolytic enzymes for removing organic pollutants. Moreover, potential problems and intriguing observations that are worthy of additional research attention are highlighted. Lastly, we discuss trends in WRF-remediation system development and avenues that should be considered to advance research in the field.

Abstract
BACKGROUND The genus Pleurotus is most exploitable xylotrophic fungi, with valuable biotechnological, medical, and nutritional properties. The relevant features of the representatives of this genus to provide attractive low-cost industrial tools have been reported in numerous studies to resolve the pressure of ecological issues. Additionally, a number of Pleurotus species are highly adaptive, do not require any special conditions for growth, and possess specific resistance to contaminating diseases and pests. The unique properties of Pleurotus species widely used in many environmental technologies, such as organic solid waste recycling, chemical pollutant degradation, and bioethanol production. METHODOLOGY The literature study encompasses peer-reviewed journals identified by systematic searches of electronic databases such as Google Scholar, NCBI, Springer, ResearchGate, ScienceDirect, and ISI Web of Knowledge. The search scheme was divided into several steps, as described below. RESULTS In this review, we describe studies examining the biotechnological feasibility of Pleurotus spp. to elucidate the importance of this genus for use in green technology. Here, we review areas of application of the genus Pleurotus as a prospective biotechnological tool. CONCLUSION The incomplete description of some fungal biochemical pathways emphasises the future research goals for this fungal culture.

Abstract
Interest in production of ligninolytic enzymes has been growing over recent years for their use in various applications such as recalcitrant pollutants bioremediation; specifically, versatile peroxidase (VP) presents a great potential due to its catalytic versatility. The proper selection of the fermentation mode and the culture medium should be an imperative to ensure a successful production by an economic and available medium that favors the process viability. VP was produced by solid-state fermentation (SSF) of Pleurotus eryngii, using the agricultural residue banana peel as growth medium; an enzymatic activity of 10,800 U L(-1) (36 U g(-1) of substrate) was detected after 18 days, whereas only 1800 U L(-1) was reached by conventional submerged fermentation (SF) with glucose-based medium. The kinetic parameters were determined by evaluating the H2O2 and Mn(2+) concentration effects on the Mn(3+)-tartrate complex formation. The results indicated that although the H2O2 inhibitory effect was observed for the enzyme produced by both media, the reaction rates for VP obtained by SSF were less impacted. This outcome suggests the presence of substances released from banana peel during the fermentation, which might exhibit a protective effect resulting in an improved kinetic behavior of the enzyme.

Abstract
Extensive research efforts have been dedicated to characterizing expression of laccases and peroxidases and their regulation in numerous fungal species. Much attention has been brought to these enzymes broad substrate specificity resulting in oxidation of a variety of organic compounds which brings about possibilities of their utilization in biotechnological and environmental applications. Research attempts have resulted in increased production of both laccases and peroxidases by the aid of heterologous and homologous expression. Through analysis of promoter regions, protein expression patterns and culture conditions manipulations it was possible to compare and identify common pathways of these enzymes' production and secretion. Although laccase and peroxidase proteins have been crystallized and thoroughly analyzed, there are still a lot of questions remaining about their evolutionary origin and the physiological functions. This review describes the present understanding of promoter sequences and correlation between the observed regulatory effects on laccase, manganese peroxidase and lignin peroxidase genes transcript levels and the presence of specific response elements.

Abstract
A new type of manganese-oxidizing enzyme has been identified in two alphaproteobacteria, "Aurantimonas manganoxydans" strain SI85-9A1 and Erythrobacter sp. strain SD-21. These proteins were identified by tandem mass spectrometry of manganese-oxidizing bands visualized by native polyacrylamide gel electrophoresis in-gel activity assays and fast protein liquid chromatography-purified proteins. Proteins of both alphaproteobacteria contain animal heme peroxidase and hemolysin-type calcium binding domains, with the 350-kDa active Mn-oxidizing protein of A. manganoxydans containing stainable heme. The addition of both Ca(2+) ions and H(2)O(2) to the enriched protein from Aurantimonas increased manganese oxidation activity 5.9-fold, and the highest activity recorded was 700 microM min(-1) mg(-1). Mn(II) is oxidized to Mn(IV) via an Mn(III) intermediate, which is consistent with known manganese peroxidase activity in fungi. The Mn-oxidizing protein in Erythrobacter sp. strain SD-21 is 225 kDa and contains only one peroxidase domain with strong homology to the first 2,000 amino acids of the peroxidase protein from A. manganoxydans. The heme peroxidase has tentatively been named MopA (manganese-oxidizing peroxidase) and sheds new light on the molecular mechanism of Mn oxidation in prokaryotes.

Abstract
A novel ligninolytic peroxidase gene (ACLnP) was cloned and characterized from a poroid brown-rot fungus, Antrodia cinnamomea. The genomic DNA of the fungus harboured two copies of ACLnP, with a length of 2111 bp, interlaced with 12 introns, while the full-length cDNA was 1183 bp, with a 66 bp signal peptide and an ORF of 990 bp. The three-dimensional molecular structure model was comparable to that of the versatile peroxidase of Pleurotus eryngii. ACLnP was cloned into vector pQE31, successfully expressed in Escherichia coli strain M15 under the control of the T5 promoter and produced a non-glycosylated protein of about 38 kDa, pI 5.42. The native and recombinant ACLnP was capable of oxidizing the redox mediator veratryl alcohol, and also decolorized bromophenol blue and 2,6-dimethoxyphenol dyes, implicating a functional extracellular peroxidase activity. The significance of discovering a functional ACLnP gene in A. cinnamomea in terms of wood degradation and colonization capacity in its unique niche is discussed.

Abstract
Versatile peroxidase from white rot fungus Bjerkandera adusta was over-expressed in a soluble form in Escherichia coli. In the constructed enzyme model based on the selected gene from B. adusta, the active sites for oxidation of Mn(2+) ions and for oxidation of aromatic substrates were identified, both characteristic for versatile peroxidase. For over-expression of the recombinant enzyme different host strains, media formulations, growth temperatures, and fusion partners were tested. With the bacterial strain BL21(DE3)pLysS cultivated at 25 degrees C in auto-induction medium and presence of heme, a soluble peroxidase with incorporated heme and activity against different substrates was obtained. By exploiting an appropriate expression system and providing suitable culture conditions, the recombinant fungal peroxidases in soluble form can be produced in bacteria.

Abstract
The plant and microbial peroxidase superfamily encompasses three classes of related protein families. Class I includes intracellular peroxidases of prokaryotic origin, class II includes secretory fungal peroxidases, including the lignin degrading enzymes manganese peroxidase (MnP), lignin peroxidase (LiP), and versatile peroxidase (VP), and class III includes the secretory plant peroxidases. Here, we present phylogenetic analyses using maximum parsimony and Bayesian methods that address the origin and diversification of class II peroxidases. Higher-level analyses used published full-length sequences from all members of the plant and microbial peroxidase superfamily, while lower-level analyses used class II sequences only, including 43 new sequences generated from Agaricomycetes (mushroom-forming fungi and relatives). The distribution of confirmed and proposed catalytic sites for manganese and aromatic compounds in class II peroxidases, including residues supposedly involved in three different long range electron transfer pathways, was interpreted in the context of phylogenies from the lower-level analyses. The higher-level analyses suggest that class II sequences constitute a monophyletic gene family within the plant and microbial peroxidase superfamily, and that they have diversified extensively in the basidiomycetes. Peroxidases of unknown function from the ascomycete Magnaporthe grisea were found to be the closest relatives of class II sequences and were selected to root class II sequences in the lower-level analyses. LiPs evidently arose only once in the Polyporales, which harbors many white-rot taxa, whereas MnPs and VPs are more widespread and may have multiple origins. Our study includes the first reports of partial sequences for MnPs in the Hymenochaetales and Corticiales.

Abstract
Lignin is the most abundant renewable source of aromatic polymer in nature, and its decomposition is indispensable for carbon recycling. It is chemically recalcitrant to breakdown by most organisms because of the complex, heterogeneous structure. The white-rot fungi produce an array of extracellular oxidative enzymes that synergistically and efficiently degrade lignin. The major groups of ligninolytic enzymes include lignin peroxidases, manganese peroxidases, versatile peroxidases, and laccases. The peroxidases are heme-containing enzymes with catalytic cycles that involve the activation by H2O2 and substrate reduction of compound I and compound II intermediates. Lignin peroxidases have the unique ability to catalyze oxidative cleavage of C-C bonds and ether (C-O-C) bonds in non-phenolic aromatic substrates of high redox potential. Manganese peroxidases oxidize Mn(II) to Mn(III), which facilitates the degradation of phenolic compounds or, in turn, oxidizes a second mediator for the breakdown of non-phenolic compounds. Versatile peroxidases are hybrids of lignin peroxidase and manganese peroxidase with a bifunctional characteristic. Laccases are multi-copper-containing proteins that catalyze the oxidation of phenolic substrates with concomitant reduction of molecular oxygen to water. This review covers the chemical nature of lignin substrates and focuses on the biochemical properties, molecular structures, reaction mechanisms, and related structures/functions of these enzymes.

Abstract
Production of recombinant versatile peroxidase in Aspergillus hosts was optimized through the modification of temperature during bioreactor cultivations. To further this purpose, the cDNA encoding a versatile peroxidase of Pleurotus eryngii was expressed under control of the alcohol dehydrogenase (alcA) promoter of Aspergillus nidulans. A dependence of recombinant peroxidase production on cultivation temperature was found. Lowering the culture temperature from 28 to 19 degrees C enhanced the level of active peroxidase 5.8-fold and reduced the effective proteolytic activity twofold. Thus, a maximum peroxidase activity of 466 U L(-1) was reached. The same optimization scheme was applied to a recombinant Aspergillus niger that bore the alcohol dehydrogenase regulator (alcR), enabling transformation with the peroxidase cDNA under the same alcA promoter. However, with this strain, the peroxidase activity was not improved, while the effective proteolytic activity was increased between 3- and 11-fold compared to that obtained with A. nidulans.

Abstract
The US Department of Energy has assembled a high quality draft genome of Phanerochaete chrysosporium, a white rot Basidiomycete capable of completely degrading all major components of plant cell walls including cellulose, hemicellulose and lignin. Hundreds of sequences are predicted to encode extracellular enzymes including an impressive number of oxidative enzymes potentially involved in lignocellulose degradation. Herein, we summarize the number, organization, and expression of genes encoding peroxidases, copper radical oxidases, FAD-dependent oxidases, and multicopper oxidases. Possibly relevant to extracellular oxidative systems are genes involved in posttranslational processes and a large number of hypothetical proteins.

Abstract
The molecular architecture of versatile peroxidase (VP) includes an exposed tryptophan responsible for aromatic substrate oxidation and a putative Mn2+ oxidation site. The crystal structures (solved up to 1.3 A) of wild-type and recombinant Pleurotus eryngii VP, before and after exposure to Mn2+, showed a variable orientation of the Glu36 and Glu40 side chains that, together with Asp175, contribute to Mn2+ coordination. To evaluate the involvement of these residues, site-directed mutagenesis was performed. The E36A, E40A, and D175A mutations caused a 60-85-fold decrease in Mn2+ affinity and a decrease in the Mn2+ oxidation activity. Transient-state kinetic constants showed that reduction of both compounds I and II was affected (80-325-fold lower k2app and 103-104-fold lower k3app, respectively). The single mutants retained partial Mn2+ oxidation activity, and a triple mutation (E36A/E40A/D175A) was required to completely suppress the activity (<1% kcat). The affinity for Mn2+ also decreased ( approximately 25-fold) with the shorter carboxylate side chain in the E36D and E40D variants, which nevertheless retained 30-50% of the maximal activity, whereas similar mutations caused a 50-100-fold decrease in kcat in the case of the Phanerochaete chrysosporium manganese peroxidase (MnP). Additional mutations showed that introduction of a basic residue near Asp175 did not improve Mn2+ oxidation as found for MnP and ruled out an involvement of the C-terminal tail of the protein in low-efficiency oxidation of Mn2+. The structural and kinetic data obtained highlighted significant differences in the Mn2+ oxidation site of the new versatile enzyme compared to P. chrysosporium MnP.

Abstract
Versatile peroxidases are heme enzymes that combine catalytic properties of lignin peroxidases and manganese peroxidases, being able to oxidize Mn(2+) as well as phenolic and non-phenolic aromatic compounds in the absence of mediators. The catalytic process (initiated by hydrogen peroxide) is the same as in classical peroxidases, with the involvement of 2 oxidizing equivalents and the formation of the so-called Compound I. This latter state contains an oxoferryl center and an organic cation radical that can be located on either the porphyrin ring or a protein residue. In this study, a radical intermediate in the reaction of versatile peroxidase from the ligninolytic fungus Pleurotus eryngii with H(2)O(2) has been characterized by multifrequency (9.4 and 94 GHz) EPR and assigned to a tryptophan residue. Comparison of experimental data and density functional theory theoretical results strongly suggests the assignment to a tryptophan neutral radical, excluding the assignment to a tryptophan cation radical or a histidine radical. Based on the experimentally determined side chain orientation and comparison with a high resolution crystal structure, the tryptophan neutral radical can be assigned to Trp(164) as the site involved in long-range electron transfer for aromatic substrate oxidation.

Versatile Peroxidase Oxidation of High Redox Potential Aromatic Compounds: Site-directed Mutagenesis, Spectroscopic and Crystallographic Investigation of Three Long-range Electron Transfer Pathways. J Mol Biol 2005; 354:385-402. [PMID: 16246366 DOI: 10.1016/j.jmb.2005.09.047] [Citation(s) in RCA: 204] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2005] [Revised: 09/09/2005] [Accepted: 09/16/2005] [Indexed: 11/16/2022]
Abstract
Versatile peroxidases (VP), a recently described family of ligninolytic peroxidases, show a hybrid molecular architecture combining different oxidation sites connected to the heme cofactor. High-resolution crystal structures as well as homology models of VP isoenzymes from the fungus Pleurotus eryngii revealed three possibilities for long-range electron transfer for the oxidation of high redox potential aromatic compounds. The possible pathways would start either at Trp164 or His232 of isoenzyme VPL, and at His82 or Trp170 of isoenzyme VPS1. These residues are exposed, and less than 11 A apart from the heme. With the purpose of investigating their functionality, two single mutations (W164S and H232F) and one double mutation (W164S/P76H) were introduced in VPL that: (i) removed the two pathways in this isoenzyme; and (ii) incorporated the absent putative pathway. Analysis of the variants showed that Trp164 is required for oxidation of two high redox potential model substrates (veratryl alcohol and Reactive Black 5), whereas the two other pathways (starting at His232 and His82) are not involved in long-range electron transfer (LRET). None of the mutations affected Mn2+ oxidation, which would take place at the opposite side of the enzyme. Substitution of Trp164 by His also resulted in an inactive variant, indicating that an indole side-chain is required for activity. It is proposed that substrate oxidation occurs via a protein-based radical. For the first time in a ligninolytic peroxidase such an intermediate species could be detected by low-temperature electron paramagnetic resonance of H2O2-activated VP, and was found to exist at Trp164 as a neutral radical. The H2O2-activated VP was self-reduced in the absence of reducing substrates. Trp164 is also involved in this reaction, which in the W164S variant was blocked at the level of compound II. When analyzing VP crystal structures close to atomic resolution, no hydroxylation of the Trp164 Cbeta atom was observed (even after addition of several equivalents of H2O2). This is in contrast to lignin peroxidase Trp171. Analysis of the crystal structures of both peroxidases showed differences in the environment of the protein radical-forming residue that could affect its reactivity. These variations would also explain differences found for the oxidation of some high redox potential aromatic substrates.

Abstract
The cloning and sequencing of the rbpa gene coding for a versatile peroxidase from a novel Bjerkandera strain is hereby reported. The 1777 bp isolated fragment contained a 1698 bp peroxidase-encoding gene, interrupted by 11 introns. The 367 amino acid-deduced sequence includes a 27 amino acid-signal peptide. The molecular model, built via homology modelling with crystal structures of four fungal peroxidases, highlighted the amino acid residues putatively involved in manganese binding and aromatic substrate oxidation. The potential heme pocket residues (R44, F47, H48, E79, N85, H177, F194 and D239) include both distal and proximal histidines (H48 and H177). RBP possesses potential calcium-binding residues (D49, G67, D69, S71, S178, D195, T197, I200 and D202) and eight cysteine residues (C3, C15, C16, C35, C121, C250, C286, C316). In addition, RBP includes residues involved in substrate oxidation: three acidic residues (E37, E41 and D183)--putatively involved in manganese binding and H83 and W172--potentially involved in oxidation of aromatic substrates. Characterisation of nucleotide and amino acid sequences include RBP in versatile peroxidase group sharing catalytic properties of both LiP and MnP. In addition, the RBP enzyme appears to be closely related with the ligninolytic peroxidases from the Trametes versicolor strain.

Abstract
Molecular phylogeny among catalase-peroxidases, cytochrome c peroxidases, and ascorbate peroxidases was analysed. Sixty representative sequences covering all known subgroups of class I of the superfamily of bacterial, fungal, and plant heme peroxidases were selected. Each sequence analysed contained the typical peroxidase motifs evolved to bind effectively the prosthetic heme group, enabling peroxidatic activity. The N-terminal and C-terminal domains of catalase-peroxidases matching the ancestral tandem gene duplication event were treated separately in the phylogenetic analysis to reveal their specific evolutionary history. The inferred unrooted phylogenetic tree obtained by three different methods revealed the existence of four clearly separated clades (C-terminal and N-terminal domains of catalase-peroxidases, ascorbate peroxidases, and cytochrome c peroxidases) which were segregated early in the evolution of this superfamily. From the results, it is obvious that the duplication event in the gene for catalase-peroxidase occurred in the later phase of evolution, in which the individual specificities of the peroxidase families distinguished were already formed. Evidence is presented that class I of the heme peroxidase superfamily is spread among prokaryotes and eukaryotes, obeying the birth-and-death process of multigene family evolution.

Abstract
Complementary DNA (cDNA) encoding the new versatile peroxidase from the ligninolytic basidiomycete Pleurotus eryngii has been expressed in the ascomycete Emericella nidulans. In recombinant E. nidulans cultures, the pH reached values as high as 8.3, correlating with a sharp decrease in peroxidase activity. Peroxidase was rapidly inactivated at alkaline pH, but was comparatively stable at acidic pH. The peroxidase inactivation in alkaline buffer could be reversed by adding Ca(2+) and lowering the pH. However, reactivation did not result after incubating the enzyme in non-buffered E. nidulans cultures that reached pH 7.5. To optimize recombinant peroxidase production, the effect of controlling the pH in E. nidulans bioreactor cultures was studied. An extended growth period, and a significant increase in the recombinant peroxidase level (5.3-fold higher activity than in the bioreactor without pH control) was obtained when the pH was maintained at 6.8, showing that culture pH is an important parameter for recombinant peroxidase production.

Abstract
Nuclear magnetic resonance spectroscopy has been used to characterize the versatile peroxidase from Pleurotus eryngii, both in the resting state and in the cyanide-inhibited form. The assignment of most of the hyperfine-shifted resonances has been achieved by two-dimensional NMR, allowing the comparison of the present system with other ligninolytic peroxidases. This information has enabled a detailed analysis of the interaction of the enzyme with one of its reducing substrates, Mn(II). Furthermore, comparison with the data collected on a mutant in the putative Mn(II) binding site, and an analysis of the enzyme kinetic properties, shed light on the factors affecting the function of this novel peroxidase.

Abstract
The effect of Mn2+ amendment on peroxidase gene expression was studied during Pleurotus ostreatus growth on cotton stalks. Four peroxidase-encoding genes were expressed differentially and in a manner different from that observed in defined media. Mn2+ affects mnp3 expression even 2 h after its addition to the cultures, suggesting a direct effect of the metal ion on expression.

Abstract
Peroxidases are oxidoreductases that utilize hydrogen peroxide to catalyze oxidative reactions. A large number of peroxidases have been identified in fungal species and are being characterized at the molecular level. In this manuscript we review the current knowledge on the molecular aspects of this type of enzymes. We present an overview of the research efforts undertaken in deciphering the structural basis of the catalytic properties of fungal peroxidases and discuss molecular genetics and protein homology aspects of this enzyme class. Finally, we summarize the potential biotechnological applications of these enzymes and evaluate recent advances on their expression in heterologous systems for production purposes.
