Webb30 mars 2024 · Cell-free protein synthesis (CFPS) is a method utilized for producing proteins without the limits of cell viability. The plug-and-play utility of CFPS is a key advantage over traditional plasmid-based expression systems and is foundational to the potential of this biotechnology. A key limitation of CFPS is the varying stability of DNA … Webb16 nov. 2007 · When RecBCD encounters Chi, the nuclease activity of the enzyme is regulated to produce a 3′-tailed duplex onto which the RecA protein is loaded to initiate repair by homologous recombination. The apparent simplicity of the overall reaction belies the underlying complexity of the events that take place during the catalytic cycle.
