Laccases are enzymes belonging to the group of multi-copper oxidases. These enzymes are widely distributed in insects, plants, fungi and bacteria. In general, laccases can oxidize an exceptionally high number of substrates, so they have broad applications in textile, pulp, food and the degradation of lignin. However, low yield, low activity and thermo-instability of laccase in nature limit the application of laccase. High efficient heterologous expression of the protein is an effective way for solving this problem. Here, we summarize the research advances of heterologous expression of eukaryote-origin laccases. We focus on the overexpression of eukaryote-origin laccases using different expression system and the method for improving the production yield and enzyme activity in yeast cells. Information provided in this review would be helpful for researchers in the field.
漆酶属于多铜氧化酶类。这些酶广泛分布于昆虫、植物、真菌和细菌中。一般来说,漆酶能氧化大量底物,因此在纺织、纸浆、食品及木质素降解等领域有广泛应用。然而,自然界中漆酶产量低、活性低和热不稳定性限制了其应用。该蛋白的高效异源表达是解决这一问题的有效途径。在此,我们总结了真核生物源漆酶异源表达的研究进展。我们重点关注利用不同表达系统对真核生物源漆酶的过表达以及提高酵母细胞中产量和酶活性的方法。本综述提供的信息将对该领域的研究人员有所帮助。
