Theoretical Study on Storage and Release of Firefly Luciferin
Photochemistry and Photobiology, 2021AbstractAmong numerous bioluminescent organisms, firefly is the most studied one. Recent experiment proposed that sulfoluciferin (SLH2) may serve as a storage form of luciferin (LH2). In the present article, we employed density functional theory calculation to uncover the mechanism and detailed process of the storage and release reactions.

Differential Effect of Azetidine Substitution in Firefly Luciferin Analogues
ChemBioChem, 2021AbstractReplacing an N,N‐dimethylamino group in a classical fluorophore with a four membered azetidine ring provides an improved luminescence quantum yield. Herein, we extended this strategy to bioluminescent firefly luciferin analogues and evaluated its general validity.

Multicolor Bioluminescence Obtained Using Firefly Luciferin
Current Topics in Medicinal Chemistry, 2016Firefly bioluminescence is widely used in life science research as a useful analysis tool. For example, the adenosine-5`-triphosphate (ATP)-dependent enzymatic firefly bioluminescence reaction has long been utilized as a microbial monitoring tool. Rapid and sensitive firefly luciferin-luciferase combinations are used not only to measure cell viability ...

Firefly luciferin as a multifunctional chemiluminescence molecule
Photochemical & Photobiological Sciences, 2013The chemiluminescence properties of firefly luciferin were studied, in a variety of chemical systems different from those in which it is usually studied. It was found that luciferin is a multifunctional chemiluminescence molecule, as it can behave as a chemiluminescence sensitizer, an emitter and a substrate.

The preparation and properties of crystalline firefly luciferin
Archives of Biochemistry and Biophysics, 1957Abstract 1. 1. The purification and preparation of crystalline firefly luciferin is described. From 15,000 firefly lanterns approximately 9 mg. of crystalline luciferin can be prepared. 2. 2. The empirical formula appears to be C13H12N2S2O3. Infrared spectra and microorganic spot tests of luciferin and various derivatives indicate that two of

A model for firefly luciferin biosynthesis
Journal of the Chemical Society, Chemical Communications, 1975The suggestion that firefly luciferin arises from p-benzoquinone and cysteine in nature offers a synthesis of the benzothiazole nucleus which may be related to a possible biosynthesis.

Dye induced quenching of firefly luciferase–luciferin bioluminescence
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2007The quenching of firefly bioluminescence (BL) in presence of xanthene dyes and tetratolylporphyrin was investigated. The BL intensity was quenched with an altered decay pattern in presence of xanthene dyes and tetratolylporphyrin. The electronic absorption spectra indicate that there is no significant interaction occurring between the dyes and the BL ...

Absorption Spectrum of the Firefly Luciferin Anion Isolated in Vacuo
The Journal of Physical Chemistry A, 2011The excited-state physics of the firefly luciferin anion depends on its chemical environment, and it is therefore important to establish the intrinsic behavior of the bare ion. Here we report electronic absorption spectra of the anion isolated in vacuo obtained at an electrostatic ion storage ring and an accelerator mass spectrometer where ionic ...

Sulfoluciferin is Biosynthesized by a Specialized Luciferin Sulfotransferase in Fireflies
Biochemistry, 2016Firefly luciferin is a specialized metabolite restricted to fireflies (family Lampyridae) and other select families of beetles (order Coleoptera). Firefly luciferin undergoes luciferase-catalyzed oxidation to produce light, thereby enabling the luminous mating signals essential for reproductive success in most bioluminescent beetles.
