1578-AGENTEX: Automated Prototyping of Genetic Codes
Researchers have developed AGENTEX, an automated robotic platform designed to prototype and test synthetic genetic codes within cell-free translation systems. This innovation relies on the discovery that natural aminoacyl tRNA synthetases possess significant flexibility, allowing them to charge engineered tRNAs even when their universal 3′ CCA terminal sequence is mutated. By pairing these non-standard tRNAs with mutant ribosomes that specifically recognize altered 3′ ends, the system creates a parallel translation channel that avoids crosstalk with the host's native machinery. To support…
