Simplified Proteins Are Giving Researchers a New Window Into Life’s Earliest Chemistry
A new review argues that proteins built from a reduced set of amino acids can still fold and function, strengthening the case that early life may have started with much simpler biochemical parts than modern organisms use
Key Takeaways
- A new review examines proteins built from reduced amino acid alphabets.
- Experiments suggest early life may not have needed the 20 amino acids used by modern biology.
