The development of chemical reactions that can distinguish between the 20 common amino acids with high specificity offers the potential to decipher the sequence, structure and function of proteins.

Non-natural proteins refer to proteins that have amino acids other than 20 canonical amino acids (non-natural amino acids) or α-hydroxy acids in place of amino acid residues at defined sites.

Scientists have analysed amino acids locked in snail shells to establish a new age for the world’s oldest complete wooden hunting weapons The study used recent advances in a dating method known as ...

Researchers demonstrated how amino acids could spontaneously attach to RNA under early Earth-like conditions using thioesters, providing a long-sought clue to the origins of protein synthesis. This ...
