摘　　要：综述了漆酶催化活性中心结构及应用的研究进展。漆酶的催化反应发生在铜离子形成的活性中心 ,但其氧化能力与氨基酸配体有密切的关系。漆酶可应用于带有羟基或氨基的芳香族单体的聚合反应 ,偶氮染料的合成及降解 ,稠环芳烃的降解去毒等。同时在纸浆的洁净漂白 ,化学分析中痕量物质的检测 。Recent advances in studies on structure of catalytic active center and application of laccase are reviewed in the present paper.Main catalytic reactions of laccase occur in Cu 2+ formed active center,however the level of redox potential is related to amino acid ligands.Laccase could catalyze polymerization of aromatic compounds with hydroxyl or amino groups,synthesis and degradation of azo dye,and degradation and detoxification of polyaromatic hydrocarbon, etc.Laccase was used in recent studies for building up total chlorine free (TCF) pulp bleaching system.In addition,laccase has been widely used in keeping fresh of foods and environmental protection processes.
