| 摘 要： | 白腐菌分泌的木质素降解酶主要有木质素过氧化物酶、锰依赖过氧化物酶和漆酶3种。漆酶属于蓝色多铜氧化酶家族,可以催化氧化多种有机化合物,伴随着分子氧还原成水,但不同来源的漆酶降解能力差异很大,而此恰与漆酶的结构密切相关。作者综述了漆酶尤其是真菌漆酶结构特征、催化活性中心和高级结构等方面的研究进展。

| Abstract: | Three different enzymes are involved in lignin degration produced by the white rot fungi,they are lignin peroxidases,manganese peroxidases and laccase.Laccase,a member of the blue multi-copper oxidase family,catalyzes the oxidation of a variety of organic substrates coupled to the reduction of molecular oxygen to water.The abilities to degrade lignin by different laccases vary widely,which depend on the structure of laccases,especially the structure of the trinuclear copper site.The structure characteristics,active site and three-dimension structure of fungal laccase weresummarized in this review. |
