Compositions and methods of making hybrid polypeptides and other polymers are disclosed. For example, functionalized tRNA having a functional molecule including a benzoic acid or benzoic acid derivative acylated to the 3' nucleotide of a tRNA are provided. Functionalized tRNA having a functional molecule including a malonic acid or malonic acid derivative acylated to the 3' nucleotide of a tRNA are also provided. Methods of using the functionalized tRNA for making compounds including the functional molecule are also provided. The methods typically include providing or expressing a messenger RNA (mRNA) encoding the target polypeptide in a translation system including one or more functionalized tRNA wherein each functionalized tRNA recognizes at least one codon such that its functional molecule is incorporated into the polypeptide or other polymer during translation. The incorporation of the functional molecule can occur in vitro in a cell-free translation system, or in vivo in a host cell.
本文揭示了制备混合
多肽和其他聚合物的组成物和方法。例如,提供了具有功能分子(包括
苯甲酸或
苯甲酸衍
生物)酰化到tRNA的3'核苷酸的功能化tRNA。还提供了具有功能分子(包括
丙二酸或
丙二酸衍
生物)酰化到tRNA的3'核苷酸的功能化tRNA。还提供了使用功能化tRNA制备包括功能分子的化合物的方法。这些方法通常包括在翻译系统中提供或表达编码目标
多肽的信使RNA(mRNA),该系统包括一个或多个功能化tRNA,其中每个功能化tRNA识别至少一个密码子,使其功能分子在翻译过程中被合并到
