A chemical substance present in the cells of bioluminescent organisms, such as fireflies, that produces an almost heatless, bluish-green light when oxidized under the catalytic effects of luciferase and ATP.

[Latin lūcifer, light-bringing; see Lucifer + -in.]


(Biochemistry) biochem a substance occurring in bioluminescent organisms, such as glow-worms and fireflies. It undergoes an enzyme-catalysed oxidation and emits light on decaying to its ground state
[C20: from Latin lucifer (literally: light-bearer) + -in]


(luˈsɪf ər ɪn)

a pigment of bioluminescent organisms that emits light while being oxidized.
[1885–90; < Latin lūcifer]

The researchers used silica nanoparticles to carry luciferase, and they used slightly larger particles of the polymers PLGA and chitosan to carry luciferin and coenzyme A, respectively.
They also used two other components called luciferin and coenzyme A.
In addition, direct ROS scavenging of hydrogen peroxide or superoxide generated were measured using Amplex Red and methyl cypridina luciferin analog (MCLA).
Adenylation of luciferin by luciferase activates the substrate for conversion to oxyluciferin and thus the resulting luminescence is proportional to ATP concentration (Manfredi et al.
Speaking to the UK newspaper, Ilia Yampolsky of the Institute of Bio-organic Chemistry, explained: "The mechanism of fungal bioluminescence suggests the formation of luciferin from a certain precursor.
The body of the bug produces a substance called luciferin.
The light comes from a chemical reaction involving the coming together of oxygen with the complex molecule luciferin, which releases the extra energy in the form of cold light.
During the course of movement, glowworm identifies its neighbors based on local-decision domain and selects a neighbor which has a luciferin value higher than its own using a probabilistic mechanism and moves toward it [44-49].
The diagnostic method of this invention comprises: detection by means of the high-pressure liquid chromatography (HPLC) technique of the Ap4A molecule, for the purposes of the calculation of which use will be made of a standard sample of Ap4A of commercial origin and of known concentration; and the use of a luminometric method for the detection and quantification of the Ap4A dinucleotide by means of the use of luciferin luciferase.
FFL(Firefly luciferase) catalyzes the oxidation of luciferin in the presence of ATP, Mg2+ and molecular oxygen to produce light, oxyluciferin, CO2 and AMP [1].
The brightness of depends on the luciferin quantity, indicating more pigment means more light.
