Abstract
Des Soye et al. create and optimize a strain of Escherichia coli that expresses T7 RNA polymerase so that lysates prepared from the strain are enriched with sufficient polymerase to catalyze high-yielding cell-free transcription and translation reactions. Using the resulting platform, the authors synthesize products containing up to 40 non-canonical amino acids.
