WebFigure 4 demonstrates the importance of minimizing co-reporter levels. Co-transfecting the Renilla co-reporter at a 10:1 (firefly:Renilla) ratio caused the firefly luciferase signal to be decreased by approximately 50%, and … Firefly luciferase is the light-emitting enzyme responsible for the bioluminescence of fireflies and click beetles. The enzyme catalyses the oxidation of firefly luciferin, requiring oxygen and ATP. Because of the requirement of ATP, firefly luciferases have been used extensively in biotechnology. See more The chemical reaction catalyzed by firefly luciferase takes place in two steps: • luciferin + ATP → luciferyl adenylate + PPi • luciferyl adenylate + O2 → oxyluciferin + AMP + light See more The protein structure of firefly luciferase consists of two compact domains: the N-terminal domain and the C-terminal domain. The N-terminal domain is composed of two β-sheets in an αβαβα structure and a β barrel. The two β-sheets stack on top of each other, with the … See more D-luciferin is the substrate for firefly luciferase's bioluminescence reaction, while L-luciferin is the substrate for luciferyl-CoA synthetase activity.
