Sulfoluciferin is Biosynthesized by a Specialized Luciferin Sulfotransferase in Fireflies
Biochemistry, 2016 Firefly 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.

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 ...

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 ...

Cage the firefly luciferin! – a strategy for developing bioluminescent probes
Chem. Soc. Rev., 2013Bioluminescent imaging (BLI) has been widely applicable in the imaging of process envisioned in life sciences. As the most conventional technique for BLI, the firefly luciferin-luciferase system is exceptionally functional in vitro and in vivo.

Analysis of Photoexcitation Energy Dependence in the Photoluminescence of Firefly Luciferin
Photochemistry and Photobiology, 2014AbstractThe whole pathways for photoluminescence, which include absorption, relaxation and emission, of firefly luciferin in aqueous solutions of different pH values with different photoexcitation energies were theoretically investigated by considering protonation/deprotonation.

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 ...

Synthesis of Firefly Luciferin Analogues and Evaluation of the Luminescent Properties
Chemistry – A European Journal, 2016AbstractFive new firefly luciferin (1) analogues were synthesized and their light emission properties were examined. Modifications of the thiazoline moiety in 1 were employed to produce analogues containing acyclic amino acid side chains (2–4) and heterocyclic rings derived from amino acids (5 and 6) linked to the benzothiazole moiety.

Important Site of Luciferin on Firefly Bioluminescence
ECS Transactions, 2008The firefly bioluminescence is well known in the world. Although its emission efficiency is assumed the best of the earth, a color variation is aspired in top science. For producing color variation, we have innovated new technology by analyzing biofunctions.

Recent progress in the synthesis of firefly luciferin derivatives
Dyes and Pigments, 2019Abstract Bioluminescent is a standard noninvasive technique for in vivo imaging. Bioluminescent screenings are based on the generation of light during interaction of luciferase with an appropriate substrate: D-luciferin (LH2), aminoluciferin (NH2-LH2) or theirs derivatives.
