Tag: Genetic code expansion

Over 200 non-canonical amino acids have been genetically incorporated into proteins using advanced genetic code expansion technologies, proving it's possible to make new amino acids. This incredible ability to expand life's building blocks is now revolutionizing biotechnology, medicine, and materials science, pushing the boundaries of what's possible.

With only 25 selenoproteins encoded in the human genome, the question of which is the 21st amino acid points to a rare but essential component of life. This unique amino acid, selenocysteine, adds a fascinating layer to our understanding of protein synthesis and genetic recoding.
