真菌天然产物包含广泛的化合物。有些在医学上具有吸引力,可以作为药物和药物先导,有些用作食品添加剂,而另一些则是有害的真菌毒素。近年来,几种真菌的基因组序列已成为可用的,提供了大量推定的生物合成途径的遗传信息。然而,化合物的发现是困难的,因为生产化合物所需的基因通常是沉默的或在实验室条件下几乎不表达。此外,大多数真菌物种缺乏可用的遗传操作工具,阻碍了途径的发现。生物合成途径在模型系统或细胞工厂中的异源表达促进了产物的发现、阐明和生产。本文综述了近年来异源表达真菌生物合成途径的研究进展。
Fungal natural products comprise a wide range of compounds. Some are medically attractive as drugs and drug leads, some are used as food additives, while others are harmful mycotoxins. In recent years the genome sequence of several fungi has become available providing genetic information of a large number of putative biosynthetic pathways. However, compound discovery is difficult as the genes required for the production of the compounds often are silent or barely expressed under laboratory conditions. Furthermore, the lack of available tools for genetic manipulation of most fungal species hinders pathway discovery. Heterologous expression of the biosynthetic pathway in model systems or cell factories facilitates product discovery, elucidation, and production. This review summarizes the recent strategies for heterologous expression of fungal biosynthetic pathways in Aspergilli.
