Abstract The bottom-up reconstruction of cellular functions has gained increasing attention for studying biological complexity, and for developing advanced biotechnological tools, including synthetic cells. A fundamental challenge is the ability to control and replicate DNA-encoded information within basic in vitro transcription-translation (IVTT) systems.

Abstract Promiscuous enzymes often serve as the starting point for the evolution of novel functions. Yet, the extent to which the promiscuity of an individual enzyme can be harnessed several times independently for different purposes during evolution is poorly reported.

Abstract In vitro metabolic systems allow the reconstitution of natural and new-to-nature pathways outside of their cellular context and are of increasing interest in bottom-up synthetic biology, cell-free manufacturing and metabolic engineering. Yet, the prototyping of such in vitro networks is very often restricted by time- and cost-intensive analytical methods.
