Metabolic engineering strategies for terpenoid production have mainly focused on bottlenecks in the supply of precursor molecules and cytotoxicity to terpenoids. In recent years, the strategies involving compartmentalization in eukaryotic cells has rapidly developed and have provided several advantages in the supply of precursors, cofactors and a suitable physiochemical environment for product storage. In this review, we provide a comprehensive analysis of organelle compartmentalization for terpenoid production, which can guide the rewiring of subcellular metabolism to make full use of precursors, reduce metabolite toxicity, as well as provide suitable storage capacity and environment. Additionally, the strategies that can enhance the efficiency of a relocated pathway by increasing the number and size of organelles, expanding the cell membrane and targeting metabolic pathways in several organelles are also discussed. Finally, the challenges and future perspectives of this approach for the terpenoid biosynthesis are also discussed.
萜类化合物生产的代谢工程策略主要集中在前体分子供应的瓶颈以及萜类化合物的细胞毒性上。近年来,涉及真核细胞区室化的策略迅速发展,并在前体供应、辅因子以及产品储存的合适物理化学环境方面提供了若干优势。在本综述中,我们对用于萜类化合物生产的细胞器区室化进行了全面分析,这可以指导亚细胞代谢的重新布线,以充分利用前体、降低代谢物毒性,并提供合适的储存能力和环境。此外,还讨论了通过增加细胞器的数量和大小、扩展细胞膜以及靶向多个细胞器中的代谢途径来提高重新定位途径效率的策略。最后,还讨论了这种方法在萜类生物合成方面的挑战和未来前景。
