AMINO ACID-MODIFIED NUCLEIC ACID AND UTILIZATION THEREOF

摘要

Provided is a method for synthesizing a protein, into which a nucleobase amino acid (NBA) is introduced at a desired position, that comprises: a step for preparing mRNA into which a modified codon is inserted at a desired position downstream of an initiation codon; and a step for translating the aforesaid mRNA into a protein in the presence of tRNA, said tRNA recognizing the modified codon and being acylated with the NBA. Also provided is a ribozyme that catalyzes the aminoacylation of tRNA and comprises two RNA molecules.
