Abstract

Because of its high specificity and stereoselectivity, cascade reactions using enzymes have been attracting attention as a platform for chemical synthesis. However, the sensitivity of enzymes outside their optimum conditions and their rapid decrease of activity upon dilution are drawbacks of the system. In this study, we developed a system for cascade enzymatic conversion in bacteria-shaped liposomes formed by hypertonic treatment, and demonstrated that the system can overcome the drawbacks of the enzymatic cascade reactions in bulk. This system produced final products at a level equivalent to the maximum concentration of the bulk system (0.10 M, e.g., 4.6 g/L), and worked even under conditions where enzymes normally lose their function. Under diluted conditions, the conversion rate of the artificial cell system was remarkably higher than that in the bulk system. Our results indicate that artificial cells can behave as a platform to perform fermentative production like microorganisms.
