The invention relates to a polypeptide comprising an amino acid having a bicyclo[6.1.0]non-4-yn-9-ylmethanol (BCN) group, particularly when said BCN group is present as: a residue of a lysine amino acid. The invention also relates to a method of producing a polypeptide comprising a BCN group, said method comprising genetically incorporating an amino acid comprising a BCN group into a polypeptide. The invention also relates to an amino acid comprising bicyclo[6.1.0]non-4-yn-9-ylmethanol (BCN), particularly and amino acid which is bicyclo[6.1.0]non-4-yn-9-ylmethanol (BCN) lysine. In addition the invention relates to a PylRS tRNA synthetase comprising the mutations Y271M, L274G and C313A.
该发明涉及一种多肽,其中包含一种具有双环[6.1.0]非-4-炔-9-基甲醇(BCN)基团的氨基酸,特别是当该BCN基团存在为:赖氨酸氨基酸的残基。该发明还涉及一种生产包含BCN基团的多肽的方法,该方法包括将含有BCN基团的氨基酸基因地合并到多肽中。该发明还涉及一种含有双环[6.1.0]非-4-炔-9-基甲醇(BCN)的氨基酸,特别是一种双环[6.1.0]非-4-炔-9-基甲醇(BCN)赖氨酸。此外,该发明涉及一种含有突变Y271M、L274G和C313A的PylRS tRNA合成酶。
