摘要：5-Aminovalerate is a potential C5 platform chemical for synthesis of valerolactam, 5-hydroxyvalerate, glutarate, and 1,5-pentanediol. It is a metabolite of l -lysine catabolism through the aminovalerate pathway in Pseudomonas putida . l -Lysine monooxygenase (DavB) and 5-aminovaleramide amidohydrolase (DavA) play key roles in the biotransformation of l -lysine into 5-aminovalerate. Here, DavB and DavA of P. putida KT2440 were expressed, purified, and coupled for the production of 5-aminovalerate from l -lysine. Under optimal conditions, 20.8 g/L 5-aminovalerate was produced from 30 g/L l -lysine in 12 h. Because l -lysine is an industrial fermentation product, the two-enzyme coupled system presents a promising alternative for the production of 5-aminovalerate.
