Abstract: The invention relates to establishment of a series of artificial luciferases based on artificial amino acid sequences extracted by amino acid alignment of copepod-derived luciferase sequences in a database based on amino acid similarity. The invention provides high luminescence intensity, high luminescence stability, and a spectrum with increased wavelength as luminescence characteristics. A series of artificial luciferases (ALuc) was established. The group of ALucs has superior luminescence characteristics, such as an increase in luminescence intensity, an increase in luminescence stability, or an increase in wavelength of the luminescence spectrum, which were not obtained before. Further, by using the artificial luciferases (ALuc) of the invention, it is possible to provide a novel, superior bioassay system, such as a bioluminescent probe, two-hybrid assay, a luminescent capsule, or the like having improved measurement function.

Abstract: The invention relates to a bioluminescent substrate suitably usable in a series of artificial luciferases (ALuc), and the invention provides a wavelength-shifted spectrum with a selective high intensity luminescence and high luminescence stability obtained by the use of the substrate together with ALuc. The luminescent substrate for ALuc obtained by the invention can be included together with a suitable luminescence solution in a luminescence kit. The bioluminescent substrate for ALuc of the invention can exhibit unprecedented excellent luminescence specificity and functionality in the conventional bioluminescence probe, two-hybrid assay, bioluminescent capsule, and reporter gene assay.
