摘要:

芳香族氨基酸(aromatic amino acid, AAA)及其衍生物具有丰富的生物学功能,广泛应用于食品、医药等众多领域。随着合成生物学的发展,利用酵母进行微生物合成已成为绿色制造的研究热点。然而,酵母合成体系面临着代谢途径通量失衡、调控精度不足、底盘适配性差等问题,制约了大规模的生产应用。综述了酵母细胞工厂合成AAA及其衍生物的代谢路径调控策略。首先梳理了AAA的核心合成路径和主要限速瓶颈;继而从静态调控、时空动态调控、系统理性指导及人工智能等多个维度,归纳了代谢途径调控手段的演进;进一步分析了模式底盘(酿酒酵母)与非常规酵母在合成方面的代谢特性;最后总结了当前挑战并展望了未来方向,以期为构建高产酵母工程菌株提供策略参考。

Abstract:

Aromatic amino acids (AAA) and their derivatives possess diverse biological functions and are widely applied in food, pharmaceutical, and other industrial sectors. With advances in synthetic biology, microbial synthesis using yeast has emerged as a research hotspot in green manufacturing. However, yeast-based production systems still face problems limiting large-scale application, including imbalanced metabolic flux, insufficient regulatory precision, and poor chassis adaptability. This review summarized recent advances in metabolic regulation strategies for the synthesis of AAA and their derivatives in yeast cell factories. Firstly, it outlined the core synthetic pathways and main rate-limiting bottlenecks of AAA; then, it summarized the evolution of metabolic pathway regulation methods from multiple dimensions such as static regulation, spatiotemporal dynamic regulation, systematic rational guidance, and artificial intelligence (AI); further, it analyzed the metabolic characteristics of model chassis (Saccharomyces cerevisiae) and unconventional yeasts in synthesis; finally, it summarized the current challenges and looked forward to future directions, with the aim of providing strategic references for the construction of high-yield yeast engineering strains.
