| Research Abstract |
It is believed that the ribosomal translation machinery does not accept D-amino acids and beta-amino acids. In this study, we investigated the incorporation of these non-proteinogenic amino acids into peptides, and found that the translation machinery actually accepts several kinds of D-amino acids as well as beta-amino acids. These results open the way for the ribosomal synthesis of novel non-standard peptides with main-chain modified groups, and would facilitate the use of these unique building blocks in peptides for drug discovery.
