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.

luciferin, in biochemistry, any of several organic compounds whose oxidation in the presence of the enzyme luciferase produces light. Luciferins vary in chemical structure; the luciferin of luminescent bacteria, for example, is completely different from that of fireflies.

2016年10月24日 · Bioluminescence (BL) is a spectacular phenomenon involving light emission by live organisms. It is caused by the oxidation of a small organic molecule, luciferin, with molecular oxygen, which is catalysed by the enzyme luciferase. In nature, there are approximately 30 different BL systems, of which …

Firefly luciferin (also known as beetle luciferin) is the luciferin, precursor of the light-emitting compound, used for the firefly (Lampyridae), railroad worm (Phengodidae), starworm (Rhagophthalmidae), and click-beetle (Pyrophorini) bioluminescent systems. [1]

Luciferins are substrates of luciferases. Firefly luciferin emits at 562 nm on reaction with oxygen, catalysed by luciferase in the presence of adenosine triphosphate (ATP) and magnesium ions, emission being directly proportional to luciferin concentration over the range 0.01-1000 nmol dm -3.

Bioluminescence imaging (BLI) is based on oxidation of a substrate (a luciferin) by an enzyme (a luciferase), which usually requires energy (FMNH2 and ATP), Mg 2 +, and oxygen to generate bioluminescent photons (Qin et al., 2010). There are five …

2023年5月5日 · The luciferin from dinoflagellate algae has been found to be a derivative of the algae’s chlorophyll — posing interesting evolutionary questions.

The name luciferin refers to a group of compounds that, when oxidised in the presence of an enzyme (luciferase), produce visible light. Each luciferin has its own luciferase — a specific enzyme which catalyses the reaction.

2021年5月24日 · Bioluminescence pertains to the capability of an organism to produce and emit light. One of the ways by which bioluminescent organisms emit light is through the luciferin-luciferase reaction system. In this system, luciferin serves as a substrate of luciferase. Luciferase is the enzyme that acts on the oxidation of luciferin.

Luciferin is the basic substrate of any bioluminescent reaction. These are the major examples of marine luciferins. Bacterial luciferin is a reduced riboflavin phosphate (FMNH 2, pictured here) which is oxidized in association with a long-chain aldehyde, oxygen, and a luciferase.
