N‐Functionalized aminoacids are important building blocks for the preparation of diverse bioactive molecules, including peptides. The development of sustainable manufacturing routes to chiral N‐alkylated aminoacids remains a significant challenge in the pharmaceutical and fine‐chemical industries. Herein we report the discovery of a structurally diverse panel of biocatalysts which catalyze the asymmetric

The present invention provides methods of efficiently producing various optically active aromatic amino acid derivatives by reacting, using an additive, a specific ester compound with an aromatic halide and zinc in the presence of a catalyst. The present invention also provides amino acid derivatives that can be produced by the methods.
In some embodiments, the present disclosure relates to mutated tRNAs in which the first letter of the anticodon has been substituted to lysidine or agmatidine, and translation systems containing the mutated tRNAs. In a specific embodiment, the present disclosure provides mutated tRNAs capable of selectively translating codon NNA. In another embodiment, the present disclosure provides translation systems capable of translating two or three types of amino acids from a single codon box. In still another embodiment, the present disclosure provides novel methods for synthesizing lysidine diphosphate, agmatidine diphosphate, and derivatives thereof.
在某些实施方案中,本公开涉及反密码子的第一个字母被替换为赖氨酸或琼脂苷的突变 tRNA,以及含有该突变 tRNA 的翻译系统。在一个具体的实施方案中,本公开提供了能够选择性翻译密码子 NNA 的突变 tRNA。在另一个实施方案中,本公开提供了能够从单个密码子盒翻译两种或三种氨基酸的翻译系统。在另一个实施方案中,本公开提供了合成二磷酸赖氨酸、二磷酸阿加匹定及其衍生物的新方法。

An objective of the present invention is to provide novel means that allow reducing the rate of mistranslation into unintended amino acids due to misreading of codons. In a number of embodiments, the present disclosure provides compositions for translation which contain a tRNA having a specific combination of bases at positions 32, 33, 37, and 38 (tRNA numbering rule) in the tRNA. According to a specific embodiment of the present disclosure, the rate of introduction of unintended amino acids due to codon misreading can be reduced.
