在异源宿主E.大肠杆菌标志着基因转移能力的成就。将20多个基因和50kb的DNA导入E.大肠杆菌进行成功的异源生物合成重建。然而,接近原生宿主的生产水平的前景需要与E.杆菌本研究采用代谢工程和基因工程相结合的方法对大肠杆菌进行了改造。coli细胞背景和支持异源红霉素形成的质粒平台。结果包括改进的质粒稳定性和对生物合成产物形成的代谢支持。具体而言,用于红霉素形成的新质粒设计允许相对于当前标准品(20%稳定性)≥89%的稳定性。此外,设计用于改善红霉素生物合成途径碳流的新菌株(称为LF01)提供了400%的滴度水平改善。
The establishment of erythromycin production within the heterologous host E. coli marked an accomplishment in genetic transfer capacity. Namely, over 20 genes and 50 kb of DNA was introduced to E. coli for successful heterologous biosynthetic reconstitution. However, the prospect for production levels that approach those of the native host requires the application of engineering tools associated with E. coli. In this report, metabolic and genomic engineering were implemented to improve the E. coli cellular background and the plasmid platform supporting heterologous erythromycin formation. Results include improved plasmid stability and metabolic support for biosynthetic product formation. Specifically, the new plasmid design for erythromycin formation allowed for ≥89% stability relative to current standards (20% stability). In addition, the new strain (termed LF01) designed to improve carbon flow to the erythromycin biosynthetic pathway provided a 400% improvement in titer level.
