Enhancement and balance of 1,4-butanediamine biosynthesis in Escherichia coli based on modular metabolic engineering
1,4-Butanediamine is an important raw material for the synthesis of engineering plastics such as Polyamide 46 with excellent performance, which is widely used in automotive, electronics and machinery manufacturing industries. In this study, Escherichia coli BL21(DE3) was used as the starting strain to systematically mo...
