Reconstitution and optimization of complex plant natural product biosynthetic pathways in microbial expression systems

Curr Opin Biotechnol. 2024 May 3;87:103136. doi: 10.1016/j.copbio.2024.103136. Online ahead of print.ABSTRACTPlant natural products (PNPs) are a diverse group of chemical compounds synthesized by plants for various biological purposes and play a significant role in the fields of medicine, agriculture, and industry. In recent years, the development of synthetic biology promises the production of PNPs in microbial expression systems in a sustainable, low-cost, and large-scale manner. This review first introduces multiplex genome editing and PNP pathway assembly in microbial expression systems. Then recent technologies and examples geared toward improving PNP biosynthetic efficiency are discussed from three aspects: pathway optimization, chassis optimization, and modular coculture engineering. Finally, the review is concluded with future perspectives on the combination of machine learning and BioFoundry for the reconstitution and optimization of PNP microbial cell factories.PMID:38705090 | DOI:10.1016/j.copbio.2024.103136
