Provided herein are, inter alia, methods for linking an mRNA molecule to a polypeptide (e.g., a peptide or a protein) by linking the mRNA molecule to a linking amino acid in the polypeptide, or by linking the mRNA molecule to a linking tRNA to which the polypeptide is attached, via reactions not catalyzed by the ribosome, and methods for making polypeptide libraries. Also provided are mRNA-protein complexes and mRNA-tRNA-protein complexes, libraries containing these complexes, and methods of using these complexes.
本文提供了将mRNA分子与
多肽(例如肽或蛋白质)连接的方法,其中通过将mRNA分子连接到
多肽中的连接
氨基酸,或通过将mRNA分子连接到连接tRNA,再将tRNA连接到
多肽上,通过非
核糖体催化的反应实现连接。同时,还提供了制备
多肽库的方法。此外,本文还提供了mRNA-蛋白质复合物和mRNA-tRNA-蛋白质复合物,以及包含这些复合物的库以及使用这些复合物的方法。
