Automated genetic tRNA expansion enables the creation of compressed genetic codes with up to 34 amino acids in cell-free systems, surpassing the standard 20.
- Why it matters: Expanding genetic codes is crucial for developing novel therapeutics, biopolymers, and understanding evolutionary possibilities, but genome recoding remains highly challenging.
- What they did: The team developed AGENTEX, a robotic method to test non-CCA-3' tRNAs for aminoacylation by natural aminoacyl tRNA synthetases, and created cell-free translation systems for 34 amino acids.
- The result: This approach successfully reprogrammed genetic codes, incorporated non-standard amino acids, and reassigned codons, paving the way for advanced synthetic biology and evolutionary studies.
