Novel Bioproduction of 1,6-Hexamethylenediamine from l-Lysine Based on an Artificial One-Carbon Elongation Cycle.

ABSTRACT: 1,6-hexamethylenediamine (HMD) is an important precursor for nylon-66 material synthesis, while research on the bioproduction of HMD has been relatively scarce in scientific literature. As concerns about climate change, environmental pollution, and the depletion of fossil fuel reserves continue to grow, the significance of producing fundamental chemicals from renewable sources is becoming increasingly prominent. In recent investigations, the bioproduction of HMD from adipic acid has been reported but with lingering challenges concerning costly raw materials and low yields. Here, we have undertaken the reconstruction of the HMD synthetic pathway within Escherichia coli, which was constituted with l-lysine α-oxidase (Raip), LeuABCD, α-ketoacid decarboxylase (KivD)
