单萜吲哚生物碱(MIA)是一类广泛的植物天然产物,其中许多已被列入世界卫生组织的基本药物清单。本地植物宿主的低产量需要更可靠的这些药物来源来满足全球需求。在这里,我们报告了一个基于酵母的平台,用于高滴度生产通用MIA前体,strictosidine。我们的补料分批平台从日用化学品香叶醇和色胺开始生产约50 mg/L的strictosidine。将微生物产生的异胡萝卜苷纯化至均匀,并进行NMR表征。此外,我们的方法能够通过进料改性的色胺来生产卤代的strictosidine类似物。MIA平台菌株能够快速获得strictosidine,用于重组和生产下游MIA天然产物。
Monoterpene indole alkaloids (MIAs) are an expansive class of plant natural products, many of which have been named on the World Health Organization’s List of Essential Medicines. Low production from native plant hosts necessitates a more reliable source of these drugs to meet global demand. Here we report the development of a yeast-based platform for high-titer production of the universal MIA precursor, strictosidine. Our fed-batch platform produces ~50 mg/L strictosidine starting from the commodity chemicals geraniol and tryptamine. The microbially produced strictosidine was purified to homogeneity and NMR characterized. Additionally, our approach enables production of halogenated strictosidine analogs through feeding modified tryptamines. The MIA platform strain enables rapid access to strictosidine for reconstitution and production of downstream MIA natural products.
