Reworked tRNAs enable protein design with up to 34 amino acids
Researchers at Harvard Medical School have developed a cell-free method called AGENTEX that allows for the design of proteins using up to 34 amino acids. This advancement bypasses the need for genome recoding, offering a faster and more scalable way to create synthetic proteins for medicine and industry.
Why it matters
This breakthrough could significantly accelerate innovation in biotechnology, drug development, and materials science.

Add as preferred source The role of tRNAs in protein production. Credit: National Human Genome Research Institute with edits by the HMS Office of Communications and External Relations Scientists have been hard at work for more than 20 years to instruct biological systems, such as E. coli cells, to produce proteins they don't naturally produce. Success could mean faster, cheaper, more innovative solutions for medicine, agriculture, materials science, environmental remediation and other industries.
The journey so far has been arduous. It seemed that the best—and possibly only—way to achieve the goal was to reprogram an organism's DNA, but that has proven fiendishly difficult and time-consuming and produces feeble results.
