    Abstract: PURPOSE: A method for enhancing expression of a target protein through co-expression of tRNA of a specific amino acid is provided to enhance productivity of specific amino acid. CONSTITUTION: A method for enhancing expression of a target protein is co-expression of a gene encoding the target protein and gene sequence encoding tRNA of a specific amino acid using recombinant microorganism. The recombinant microorganism is obtained by transforming with the gene encoding the target protein and gene sequence encoding tRNA. The target protein is repetitive protein having repetitive structure of a specific oligopeptide. The repeat protein is elastin, silk protein, byssus, flagelliform silk, dragline silk, collagen, keratin, sericin or synthetic repetitive protein. The recombinant microorganism is E.coli. The recombinant vector contains T7 promoter.
