Continuous in situ synthesis of a complete set of tRNAs sustains steady-state translation in a recombinant cell-free system

Sebastian Maerkl

Construction of a self-regenerating biochemical system is critical for building a synthetic cell. An essential step in building a self-regenerative system is producing a complete set of tRNAs for translation, which remains a significant challenge. Here, we ...

Towards Self-regeneration: Exploring the Limits of Protein Synthesis in the Protein Synthesis Using Recombinant Elements (PURE) Cell-free Transcription-Translation System

Sebastian Maerkl, Ragunathan Bava Ganesh

Self-regeneration is a key function of living systems that needs to be recapitulated in vitro to create a living synthetic cell. A major limiting factor for protein self-regeneration in the PURE cell-free transcription-translation system is its high protei ...
