various non-natural amino acids as artificial substrates can be enzymatically introduced only at the basic N-terminus of any kind of acceptor peptides/proteins by using Escherichia coli leucyl/phenylalanyl-tRNA-protein transferase (L/F-transferase) without any engineering of its catalytic pocket. Extension of this L/F-transferase-mediated functionalization of peptides/proteins in combination with aminoacyl-tRNA synthetase (ARS) mutant. Fast enzymatic introduction of a positron emission tomography (PET) probe into acceptor peptides/proteins, it is site-specifically introduced at the basic N-terminus of the acceptors by using L/F-transferase in combination with aminoacyl-tRNA synthetase, namely the NEXT-A/PET reaction. Estimated from kinetic analysis, the transfer efficiency of O-(2-fluoromethyl)-L-tyrosine as an artificial amino acid PET probe mediated by the wild-type transferase is almost as good as that of the natural substrate, phenylalanine. About 90 % of Lys-Ala-7-amino-4-methylcoumarin peptide or of Lys-bradykinin peptide are labeled by O-(2-fluoromethyl)-L-tyrosine (FMT), the model protein Lys-SoCBM13 is also labeled by FMT
