    摘要:

    目的 探索柑橘活性成分柚皮苷的生物合成方法。方法 通过酶筛选、多拷贝整合以及前体供给策略构建合成柚皮素的酿酒酵母工程菌株。在此基础上通过引入柚皮苷合成途径、优化UDP-葡萄糖供应并最终实现从D-木糖合成柚皮苷。结果 通过筛选柚皮素途径关键酶确认最优黄酮合成酶为PhCHS。进一步将柚皮素合成途径整合至多拷贝位点,构建的菌株Z39M2能够合成36.53 mg/L柚皮素;过表达CAT2xPK-PTA途径和ACC1m优化丙二酰辅酶A供应构建菌株Z44,其柚皮素产量提高至72.96 mg/L;通过引入柚皮苷合成途径成功合成了35.60 mg/L柚皮苷,进一步过表达PGM1UGP1将柚皮苷产量提升至76.67 mg/L。结论 通过代谢工程策略构建了一株能够从D-木糖合成柚皮苷的酿酒酵母工程菌株。

    Abstract:

    Objective To explore the biosynthesis method of naringin, a bioactive compound in citrus.Methods Engineered Saccharomyces cerevisiae strains for naringenin biosynthesis are constructed through enzyme screening, multi-copy integration, and precursor supply. Subsequently, de novo biosynthesis of naringin from D-xylose is achieved by introducing the naringin biosynthetic pathway and optimizing UDP-glucose supply.Results The optimal flavonoid synthase is identified as PhCHS by screening the key enzymes of the naringenin pathway. The naringenin biosynthesis pathway is further integrated at multi-copy sites. The constructed strain Z39M2 can synthesize 36.53 mg/L naringenin. The overexpression of CAT2, xPK-PTA pathway, and ACC1m optimizes malonyl-CoA supply and constructs strain Z44, with a naringenin production increasing to 72.96 mg/L. Finally, the naringin biosynthesis pathway introduction enables the successful biosynthesis of 35.60 mg/L naringin. Further overexpression of PGM1 and UGP1 elevates naringin production to 76.67 mg/L.Conclusion An engineered S. cerevisiae strain capable of de novo biosynthesis of naringin from D-xylose is successfully constructed by metabolic engineering.
