  • In this technique, one peptide fragment is attached to the terminal cysteine group (sulfur-containing amino acid) of a second peptide fragment by means of a thioester group-a selective reaction that results in a natural peptide bond.


  • These peptides interact with the same nucleobases found in DNA, but each nucleobase is bound to an organic compound known as a thioester. - latest science and technology news stories

  • Expression of linear peptides bearing a cysteine-proline dipeptide sequence followed by glycolic acid results in self-rearrangement to a C-terminal diketopiperadine-thioester, which non-enzymatically generates a cyclized peptide.
