Cell-free transcription–translation (TXTL) has recently emerged as a versatile technology to engineer biological systems. In this chapter, we show how an all E. coli TXTL system can be used to build synthetic cell prototypes. We describe methods to encapsulate TXTL reactions in cell-sized liposomes, with an emphasis on the composition of the external solution and lipid bilayer. Cell-free expression is quantitatively described in bulk reactions and liposomes for three proteins: the soluble reporter protein eGFP, the membrane proteins alpha-hemolysin (AH) from Staphylococcus aureus, and the mechanosensitive channel of large conductance (MscL) from E. coli.
