Outline of Final Research Achievements |
In this study, in order to make it possible to introduce a wide variety of nonnatural amino acids into peptides and proteins, we developed four-base codon decoding system in which the genetic code originally consisted of 3 letters is expanded to 4 letters. As a result, we found that a large number of four-base codons can be used for the introduction of nonnatural amino acids, and established a method for collectively evaluating the translation efficiency of four-base codons.

Academic Significance and Societal Importance of the Research Achievements |
本研究成果は、生物の基本原理である遺伝暗号が大幅に拡張できることを明らかにしたとともに、多種多様な非天然アミノ酸からなるペプチドやタンパク質の生合成を可能にするものである。本手法は、ペプチド創薬技術と組み合わせることで、多様な非天然アミノ酸からなるペプチドの中から特定の標的分子に結合するペプチドを取得することを可能にし、新たなペプチド医薬の取得などへの応用が期待される。
