摘要:The present disclosure discloses a recombinant Escherichia coli for producing rosmarinic acid and application thereof, belonging to the technical fields of genetic engineering and bioengineering. In the present disclosure, FjTA derived from Flavobacterium johnsoniae, endogenous hpaBC derived from E. coli, CbRAS derived from Coleus blumei, HPPR derived from Coleus scutellarioides, and Pc4CL1 derived from Petroselinum crispum are heterologously expressed in E. coli, realizing synthesis of rosmarinic acid. TcTAL derived from Trichosporon cutaneum and tyrC for removing feedback inhibition are introduced, further increasing synthesis throughput of caffeic acid, and PmLAAD derived from Proteus myxofaciens is heterologously expressed, realizing redistribution of L-DOPA. An endogenous gene menl is knocked out, improving the content and stability of a rosmarinic acid precursor. The recombinant strain constructed in the present disclosure can produce rosmarinic acid by fermentation at a yield of up to 511.2 mg/L, providing a new method for industrial production of rosmarinic acid.
