[ Function ]
1. It can be used in wine clarification, bread baking, and other applications to improve food quality.
2. It can reduce the discomfort caused by inflammation and promote wound healing.
3. It can also serve as a biological element for detecting phenolic compounds.
4. It is a natural antioxidant with anti-inflammatory and anti-allergic properties, effectively alleviating the symptoms of urticaria.
5. It can be used to treat industrial wastewater, such as dye wastewater and pulping wastewater, to improve water quality and reduce environmental pollution.
6. In the papermaking and biomass energy industries, laccase can efficiently decompose lignin, increasing the accessibility of cellulose.

[ Application ]
1. Biocatalysis: 
Due to its broad substrate spectrum and high catalytic activity, laccase is widely used in biotransformations and the synthesis of various organic compounds.
2. Environmental Protection: 
Laccase can oxidize and degrade various toxic and hazardous organic pollutants, such as phenols, aromatic hydrocarbons, and chlorinated organic compounds, thereby reducing environmental pollution. It can also be used to treat industrial wastewater, such as dye wastewater and pulping wastewater, to improve water quality.
3. Textile Printing and Dyeing and Leather Processing: 
In the textile printing and dyeing industry, laccase can be used for redox reactions to decolorize and degrade dyes. In leather processing, it can be used in processes such as tanning and dyeing, improving product quality and environmental performance.
4. Food Processing and Biomedicine: 
In food processing, laccase can be used in the synthesis of food additives and the extraction and separation of natural products. In the biomedical field, it can be used in research areas such as drug design and biomarkers, providing new insights and methods for disease diagnosis and treatment.

About Laccase
Laccase is a multi-copper oxidase, its molecular structure consisting of a tetrahedral structure formed by four copper ions and four conserved nitrogen-oxygen ligands. This structure confers unique catalytic properties on laccase.
Laccase exists as a monomeric glycoprotein and is widely distributed in fungi, bacteria, and plants, particularly mushrooms, fungi, and higher plants.
The unique catalytic properties of laccase have led to its widespread application in bioassays, making it an effective tool and means for analyzing substrates, coenzymes, inhibitors, and other components as efficient biodetectors.
Laccase can oxidize polyphenols, promote methoxyl substitution of phenols and diamines, and oxidize nearly all substrates with a structure similar to that of rho-polyphenols. In addition, some fungal laccases can also oxidize monophenols such as cresol and ascorbic acid.
