Firefly luciferases
WebIn the DLR™ Assay, the activities of firefly (Photinus pyralis) and Renilla (Renilla reniformis, also known as sea pansy) luciferases are assured sequentially from adenine single sample. That firefly luciferase reporter is measured first by adding Luciferase Assay Reagent II (LAR II) to generate adenine stabilized luminescent light. WebModified/Novel Luciferases. AkaLuc: A modified firefly luciferase engineered to use the red-shifted substrate Akalumine with significantly brighter signal and emission in the near-infrared range, enabling enhanced bioluminescence imaging in vivo.; Luciferases with tunable wavelengths: NanoLuc® with either SNAP‐tag or HaloTag7 tag in which labeling …
Firefly luciferases
Did you know?
A variety of organisms regulate their light production using different luciferases in a variety of light-emitting reactions. The majority of studied luciferases have been found in animals, including fireflies, and many marine animals such as copepods, jellyfish, and the sea pansy. However, luciferases have been studied in luminous fungi, like the Jack-O-Lantern mushroom, as well as examples in other kingdoms including bioluminescent bacteria, and dinoflagellates.

WebSep 22, 2024 · Luciferases make up a class of oxidative enzymes found in several species that enable the organisms that express them to “bioluminesce,” or emit light. The most famous one of these enzymes is … 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 See more D-luciferin is the substrate for firefly luciferase's bioluminescence reaction, while L-luciferin is the substrate for luciferyl-CoA synthetase activity.
