|Coelenterazine-Utilizing Luciferase Reporters with Extremely Stable Glow-Type Bioluminescent Signal
Luminescence reporters are useful and popular tools in research and biotechnologies, allowing easy-to-use, rapid, safe, and sensitive monitoring of biological, biochemical, and chemical processes by measuring an optical signal. The luminescence process is initiated by the excitation of luminescent molecules to a high-energy state. Return to the ground state with lower energy is accompanied by the release of a photon, observable as light emission.
Bioluminescence is a fascinating phenomenon involving the emission of light by a living creature. There is enormous interest in harnessing bioluminescent systems to design ultrasensitive optical bioassays.
Despite many advances and improvements in luciferases, two major limitations are preserved. I. the flash-type of the signal with a short half-life prevents prolonged signal collection and analyses. II. moderate substrate affinity does not allow analyses at lower substrate concentrations with the maintained level of the detected signal.
The present invention relates to modified protein sequences of coelenterazine-utilizing Renilla-type luciferases utilizing widely accessible, non-cytotoxic, and low-cost coelenterazine luciferin. These novel luciferases exhibit extremely stable glow-type light emission, high substrate affinity, low product inhibition factor, and modulated emission maximum. The luciferases are designed to provide ultrasensitive and stable bioluminescent signals in a wide range of laboratory applications and bioassay formats.
