| physiological function | beetle bioluminescence is the result of two half-reactions catalyzed by a luciferase (Luc) in which the substrate D-firefly luciferin is converted into the corresponding adenylate D-firefly luciferin-AMP, followed by a multistep oxidative process that produces light via a single electron transfer process. Among the Lampyridae, one of the three families of bioluminescent beetles, light emission typically ranges from green to yellow-green in color having emission maxima (lambdamax) of about 548-568 nm | Photinus pyralis |
