摘要
三萜类化合物具有多种生物活性,被广泛应用于制药、食品、化妆品和化工行业。传统上,三萜类化合物是通过化学合成和植物提取获得的。然而,这些方法都存在高能耗、环境污染和耗时长等缺点。最近,三萜类化合物在微生物细胞工厂中实现了从头合成。这是替代传统供应方法的一种前景广阔的环保方法。酿酒酵母以其稳健、安全和充足的前体供应而著称,是三萜类生物合成的理想候选者。然而,三萜类生物合成的工业化生产和经济可行性仍面临挑战。因此,新陈代谢工程方法已被用于提高三萜类化合物的产量,并取得了重大进展。本综述探讨了三萜类化合物在 S. cerevisiae 中的生物合成机制和高效生产策略。最后,该综述还讨论了当前面临的挑战,并提出了潜在的解决方案,为未来的工程提供了启示。
Efficient Plant Triterpenoids Synthesis in Saccharomyces cerevisiae: from Mechanisms to Engineering Strategies
Triterpenoids possess a range of biological activities and are extensively utilized in the pharmaceutical, food, cosmetic, and chemical industries. Traditionally, they are acquired through chemical synthesis and plant extraction. However, these methods have drawbacks, including high energy consumption, environmental pollution, and being time-consuming. Recently, the de novo synthesis of triterpenoids in microbial cell factories has been achieved. This represents a promising and environmentally friendly alternative to traditional supply methods. Saccharomyces cerevisiae, known for its robustness, safety, and ample precursor supply, stands out as an ideal candidate for triterpenoid biosynthesis. However, challenges persist in industrial production and economic feasibility of triterpenoid biosynthesis. Consequently, metabolic engineering approaches have been applied to improve the triterpenoid yield, leading to substantial progress. This review explores triterpenoids biosynthesis mechanisms in S. cerevisiae and strategies for efficient production. Finally, the review also discusses current challenges and proposes potential solutions, offering insights for future engineering.
