A simplified and highly efficient cell-free protein synthesis system for prokaryotes.

An optimized E. coli cell-free protein synthesis system reduces reaction components from 35 to 7, boosting efficiency and simplifying preparation for diverse applications.

• Why it matters: Current prokaryotic CFPS systems are complex and difficult to optimize, limiting their widespread use in research and biotechnology. Simplifying these systems can accelerate their adoption and expand their capabilities.
• What they did: The authors systematically screened and optimized seven core reaction components and developed a rapid 'fast lysate' protocol that omits traditional steps, enabling easier and faster extract preparation.
• The result: The streamlined e CFPS system maintains or enhances protein yields, successfully synthesizes challenging proteins like vimentin and Bsa I, and offers a robust, accessible platform for various scientific and industrial uses.
