Patent number: 8715984Abstract: In the method for introducing a noncanonical amino acid residue into a desired position in a protein, the structure of tRNA is so modified as to have improved affinity for aminoacyl-tRNA synthetase or improved specificity to aminoacyl-tRNA synthetase. An unnatural base is contained at any position in tRNA, whereby the efficiency of aminoacylation of the tRNA with a noncanonical amino acid can be improved.Type: GrantFiled: February 3, 2009Date of Patent: May 6, 2014Assignee: RikenInventors: Shun-ichi Sekine, Ryuya Fukunaga, Shigeyuki Yokoyama, Ichiro Hirao, Yoko Harada
