Bioluminescence is a form of “cold light” in living organisms, based on the chemical reaction; that is, the measured light activity depends on the amount of enzyme (luciferase), substrate (luciferin), and cofactor(s). The structural relationship between luciferin and luciferase is restricted in each bioluminescence reactions. For instance, the beetle luciferase cannot catalyze the oxidation of coelenterazine (Renilla luciferin). In beetle bioluminescence, ATP is a cofactor depending on the intensity of light signal although ATP is not cofactor on other bioluminescence systems. In this talk, I explain the basic of bioluminescence system. I focus the characteristic properties of firefly luciferase and other luciferase etc.
