Cell-free protein synthesis systems provide facile access to proteins in a nascent state that enables formation of soluble, native protein-protein complexes even if one of the protein components is prone to self-aggregation and precipitation. Combined with selective isotope-labeling, this allows the rapid analysis of protein-protein interactions with few15N-HSQC spectra. The concept is demonstrated with binary and ternary complexes between the χ, ψ and γ subunits of Escherichia coli DNA...[Show more]
