Luciferin (from Latin lucifer 'light-bearer') is a generic term for the light-emitting compound found in organisms that generate bioluminescence. Luciferins typically undergo an enzyme -catalyzed reaction with molecular oxygen .
Firefly luciferin (also known as beetle luciferin) is the luciferin, precursor of the light-emitting compound, ... Crystal luciferin was found to be fluorescent, ...
A dinoflagellate luciferase is capable of emitting light due to its interaction with its substrate and the luciferin-binding protein (LBP) in the scintillon organelle found in dinoflagellates. [10] The luciferase acts in accordance with luciferin and LBP in order to emit light but each component functions at a different pH.
Coelenterazine is a luciferin found in many different marine phyla from comb jellies to vertebrates. Like all luciferins, it is oxidised to produce light. Like all luciferins, it is oxidised to produce light.
D-luciferin is the substrate for firefly luciferase's bioluminescence reaction, while L-luciferin is the substrate for luciferyl-CoA synthetase activity. Both reactions are inhibited by the substrate's enantiomer: L-luciferin and D-luciferin inhibit the bioluminescence pathway and the CoA-ligase pathway, respectively. [ 3 ]
Vargulin, [1] also called Cypridinid luciferin, [2] Cypridina luciferin, or Vargula luciferin, is the luciferin found in the ostracod Cypridina hilgendorfii, also named Vargula hilgendorfii. [3] These bottom dwelling ostracods emit a light stream into water when disturbed presumably to deter predation.
In the presence of oxygen, luciferase catalyzes the oxidation of an organic molecule called luciferin. [13] Though bio-luminescence across a diverse range of organisms such as bacteria, insects, and dinoflagellates function in this general manner (utilizing luciferase and luciferin), there are different types of luciferin-luciferase systems.
The dinoflagellete type of luciferin used in this reaction is one of the four common types of luciferin found in the marine environment, [11] and the genome of P. fusiformis contains shared common origin with other dinoflagellates that contain the luciferase enzyme. [5] In the laboratory, two different types bioluminescent flashes have been ...
