Abstract

Ribosomally synthesized lanthionine-containing peptides (lanthipeptides) have emerged as a promising source of antimicrobials against multidrug resistance pathogens. An effective way to discover and engineer lanthipeptides is through heterologous expression of their biosynthetic gene clusters (BGCs) in a host of choice. Here we report a plug-and-play pathway refactoring strategy for rapid evaluation of lanthipeptide BGCs in Bacillus subtilis based on the T7 expression system. As a proof of concept, we used this strategy to not only observe the successful production of a known lanthipeptide haloduracin β but also discover two new human-microbiota-derived lanthipeptides that previously failed to be produced in Escherichia coli. The resulting B. subtilis plug-and-play T7 expression system should enable the genome mining of new lanthipeptides in a high-throughput manner.

在枯草芽孢杆菌中异源生产多肽的即插即用 T7 表达系统

核糖体合成的含兰硫宁肽（兰硫肽）已成为一种很有前景的抗菌剂，可用于对抗具有多重耐药性的病原体。发现和设计含兰硫宁肽的有效方法是在宿主中异源表达其生物合成基因簇（BGC）。在此，我们报告了一种即插即用的路径重构策略，该策略基于 T7 表达系统，可在枯草芽孢杆菌中快速评估anthipeptide BGCs。作为概念验证，我们利用这一策略不仅观察到了已知anthipeptide haloduracin β的成功生产，还发现了两种新的源自人类微生物区系的anthipeptide，这两种anthipeptide以前在大肠杆菌中无法生产。由此产生的枯草杆菌即插即用 T7 表达系统将能以高通量的方式进行新兰肽的基因组挖掘。
