Luciferins, Bioluminescent Substances

Angewandte Chemie International Edition in English, 1968
AbstractThe bioluminescence of the American firefly Photinus is due to the reaction of 2‐(6‐hydroxybenzothiazol‐2‐yl)‐Δ2‐1,3‐thiazoline‐4‐carboxylic acid (“firefly luciferin”) with the enzyme luciferase in the presence of ATP and magnesium ion. In the crustacean Cypridina, on the other hand, the bioluminescence is due to the reaction of a luciferase ...

Isolation studies with Cypridina luciferin

Archives of Biochemistry and Biophysics, 1961
Abstract An attempt to isolate Cypridina luciferin in pure form has been made. The most promising approaches have involved the use of countercurrent distribution and membrane diffusion. Although the final objective was not realized because of instability and lack of material, the experiments strongly indicated the active chromophore to be a low ...

Mechanism of the Luminescent Oxidation of Cypridina Luciferin

Biochemical and Biophysical Research Communications, 1971
In an aqueous medium with Cypridina luciferase, or in an aprotic solvent without luciferase, the aerobic oxidation of Cypridina luciferin is accompanied by emission of light (1,2,3). The products of the luminescent oxidation have been reported as oxyluciferin and CO2 (4,5,6), although the oxyluciferin can be further converted to etioluciferin by acid ...

An Interphylum Luciferin-Luciferase Reaction

Science, 1960
The light-emitting enzyme-substance systems, heretofore separated from different types of luminescent organisms, exhibit a marked biological specificity and comprise chemically different components. Extracts from a luminescent fish are now found to cross react with a crustacean system; some properties of the new system and implications of the ...

Bacterial and Other "Luciferins"

BioScience, 1975
Although luminous bacteria were among the very first of bioluminescent organisms to be made the subject of scientific research (Boyle 1667a,b), only recently has a satisfactory answer to one of the most puzzling aspects of bacterial luminescence become firmly established (McCapra and Hysert 1973, Dunn et al. 1973, Shimomura et al. 1972, 1974, Vigny and

Novel Heterocyclic Analogues of Firefly Luciferin

Biochemistry, 2012
Five novel firefly luciferin analogues in which the benzothiazole ring system of the natural substrate was replaced with benzimidazole, benzofuran, benzothiophene, benzoxazole, and indole were synthesized. The fluorescence, bioluminescence, and kinetic properties of the compounds were evaluated with recombinant Photinus pyralis wild type luciferase ...

Clinical and biochemical applications of luciferases and luciferins

Analytical Biochemistry, 1988
Recent advances in the analytical applications of bacterial and firefly luciferases and firefly luciferin are reviewed. Luciferases have been used in soluble and immobilized/co-immobilized forms in assays for a variety of enzymes, substrates, and cofactors.
