Ultrasound and defect engineering-enhanced nanozyme with high laccase-like activity for oxidation and detection of phenolic compounds and adrenaline.

Journal of Hazardous Materials, 2023
Perusing metal-based redox nanozyme offers new opportunity for pollutant removal and biosensor, but ultrasound (US)-driven laccase-like nanozyme remains a significant challenge, especially in combination with defect engineering strategy.

Production of hydroxyl radicals following water-level drawdown in peatlands: A new induction mechanism for enhancing laccase activity in carbon cycling

, 2021
The hydroxyl radical (•OH) is the most powerful reactive oxygen species that plays a critical role in the fate of redox-active substances. Peatlands are carbon-rich ecosystems with highly reduced substances and ubiquitous redox interfaces.

Supramolecular assembly of benzophenone alanine and copper presents high laccase-like activity for the degradation of phenolic pollutants.

Journal of Hazardous Materials, 2022
Laccases are multicopper oxidases of significant importance for the degradation of phenolic pollutants. Because of the inherent defects of natural laccases in practical applications, herein, we discovered highly effective and non-cytotoxic laccase-like ...

Design, Synthesis, and Biological Activity of Novel Fungicides Containing a 1,2,3,4-Tetrahydroquinoline Scaffold and Acting as Laccase Inhibitors.

Journal of Agricultural and Food Chemistry, 2022
Laccase is a novel target for fungicides. We previously developed a new fungicide, 4-chlorocinnamaldehyde thiosemicarbazide (PMDD-5Y), as a laccase inhibitor.

Laccase activity and putative laccase genes in marine-derived basidiomycetes

Fungal Biology, 2010
Studies of laccases from marine-derived fungi are limited. In the present work, putative laccase genes from three marine-derived basidiomycetes and their laccase activities were evaluated. High amounts of laccase were produced by the fungal strains Marasmiellus sp. CBMAI 1062 (971.2UL⁻¹) and Peniophora sp.

Laccase-catalyzed soy protein and gallic acid complexation: Effects on conformational structures and antioxidant activity.

Food Chemistry, 2021
The ability of laccase to oxidize polyphenols arouses our interest that laccase can be applied for protein-polyphenol cross-linking. In this study, laccase promoted the cross-linking of gallic acid (GA) and soy protein isolate (SPI) under neutral pH. SPI-

Metal-activated laccase promoters

2002
Production of laccase isoenzymes POXC and POXAlb in the white rot basidiomycete Pleurotus ostreatus is induced by copper at the level of gene transcription, poxc and poxalb promoter regions, extending 200 nucleotides upstream of the ATG, contain multiple putative metal responsive elements (MREs) similar to the core MRE consensus sequence identified in ...

Laccase and tyrosinase activities in lichens

Microbiology, 2006
Phenoloxidase activity was found in lichenized ascomycetes belonging to different taxonomic groups. Most of the epigeic and epilithic lichens of the order Peltigerales were found to possess both laccase and tyrosinase activities; the lichens of the order Lecanorales possessed only laccase activity, which was an order of magnitude lower than that of ...

A Novel Method for Improving Laccase Activity by Immobilization onto Copper Ferrite Nanoparticles for Lignin Degradation.

International Journal of Biological Macromolecules, 2019
In this paper, a novel method for simultaneous enhancement of catalytic activity and reusability of laccase was carried out to overcome the limitations on industrial application of laccase.
