Patent number: 10287556Abstract: A luciferase that includes an amino acid sequence in which a mutation is introduced into an amino acid sequence of a luciferase derived from Luciora kuroiwae. The luciferase catalyzes a luminescence reaction that generates luminescence having the maximum luminescent wavelength of 570 nm to 610 nm. The luminescence has an intensity at least 10 times higher than that of luminescence generated in a luminescence reaction catalyzed by a luciferase derived from Rhagophthalmus ohbai.Type: GrantFiled: March 29, 2017Date of Patent: May 14, 2019Assignee: OLYMPUS CORPORATIONInventor: Katsunori Ogo

Publication number: 20170204379Abstract: A luciferase according to an embodiment comprises an amino acid sequence in which a mutation is introduced into an amino acid sequence of SEQ ID NO: 38. The luciferase catalyzes a luminescence reaction that generates luminescence having the maximum luminescent wavelength of 570 nm to 610 nm. The luminescence has an intensity at least 10 times higher than that of luminescence generated in a luminescence reaction catalyzed by a luciferase having an amino acid sequence of SEQ ID NO: 48.Type: ApplicationFiled: March 29, 2017Publication date: July 20, 2017Applicant: OLYMPUS CORPORATIONInventor: Katsunori OGO
