Definitions for luciferinluˈsɪf ər ɪn
This page provides all possible meanings and translations of the word luciferin
pigment occurring in luminescent organisms (as fireflies); emits heatless light when undergoing oxidation
any of several substances found in luminescent organisms (such as the firefly, Photinus pyralis) which, when oxidized, produces an almost heatless light. It was first isolated from fireflies, and is the source of the firefly luminescence. See also firefly luciferin
Any of a class of polycyclic heterocycles that are responsible for the bioluminescence of fireflies, being converted to oxyluciferin by luciferase in the process.
Luciferins are a class of light-emitting heterocyclic compounds found in organisms that cause bioluminescence. Luciferins typically undergo an enzyme-catalysed oxidation and the resulting unstable reaction intermediate emits light upon decaying to its ground state. The term luciferin is also used generically to refer both to the molecules that react with luciferases to emit light and to photoprotein, which emits light without the intervention of an enzyme.
