    Abstract:
    Bacterial transporters mediate the exchanges between intracellular and extracellular environments. Modification of transport route could be applied to speed up the metabolic reactions and promote the production of aimed compounds. Herein, lysine 2-monooxygenase (DavB) and δ-aminovaleramidase (DavA) were co-expressed in Escherichia coli BL21(DE3) to produce nylon-5 monomer 5-aminovalerate from l-lysine. Then, PP2911 (4-aminobutyrate transporter in Pseudomonas putida) and LysP (the lysine specific permease in E. coli) were overexpressed to promote 5-aminovalerate production using whole cells of recombinant E. coli. The constructed E. coli strain overexpressing transport proteins exhibited good 5-aminovalerate production performance and might serve as a promising biocatalyst for 5-aminovalerate production from l-lysine. This strategy not only shows an efficient process for the production of nylon monomers but also might be used in production of other chemicals.
