漆酶（benzeneoxygen oxidoreductases，EC 1.10.3.2）是多酚氧化酶（PPO），其通过使用分子氧作为电子受体催化各种取代的酚类化合物的氧化。漆酶作用于多种底物的能力使其成为各种生物技术应用中非常有用的生物催化剂。迄今为止，漆酶主要是从植物和真菌中分离和表征的，目前只有真菌漆酶用于生物技术应用。相比之下，人们对细菌漆酶知之甚少，尽管最近全基因组分析的快速进展表明这种酶广泛存在于细菌中。由于细菌遗传工具和生物技术过程已经建立，因此开发细菌漆酶将非常重要。本文综述了漆酶在细菌中的分布、功能、与真菌漆酶的比较及其应用。
Laccases (benzenediol oxygen oxidoreductases, EC 1.10.3.2) are polyphenol oxidases (PPO) that catalyze the oxidation of various substituted phenolic compounds by using molecular oxygen as the electron acceptor. The ability of laccases to act on a wide range of substrates makes them highly useful biocatalysts for various biotechnological applications. To date, laccases have mostly been isolated and characterized from plants and fungi, and only fungal laccases are used currently in biotechnological applications. In contrast, little is known about bacterial laccases, although recent rapid progress in the whole genome analysis suggests that the enzymes are widespread in bacteria. Since bacterial genetic tools and biotechnological processes are well established, so developing bacterial laccases would be significantly important. This review summarizes the distribution of laccases among bacteria, their functions, comparison with fungal laccases and their applications.
