Outline of Final Research Achievements |
Luciferin-luciferase (L-L) reactions of firefly and ostracod bioluminescence are widely applied for biological analysis and imaging. To support the development of their applications, we need to understand the mechanisms of the L-L reactions made up by several elemental processes. For the purpose, we carried out mechanistic studies on the three important processes, oxygenation, chemiexcitation, and emission from the excited oxyluciferins in the L-L reactions. The results provide information on the molecular mechanisms to design luciferin derivatives with high-performance luminescence property.
