Non-natural labeled amino acid and method of constructing amino acid/tRNA complex

摘要

This invention relates to: a labeled amino acid that can be introduced into a protein with the aid of a protein synthesis system; a functional protein having functions derived from a label compound; a labeled amino acid comprising an aromatic ring bound to an amino acid side chain and a label compound bound thereto via the aromatic ring; a functional protein to which the labeled amino acid has been introduced; and a novel method for effectively obtaining a labeled amino acid-tRNA complex.
