Water soluble form of luciferin. Luciferins are a class of small-molecule substrates that are oxidized in the presence of the enzyme luciferase to produce oxyluciferin and energy in the form of light. Luciferin undergoes an enzyme-catalysed oxidation and the resulting unstable reaction intermediate emits light upon decaying to its ground state. Firefly luciferin is the luciferin found in many Lampyridae species. It is the substrate of luciferase responsible for the characteristic yellow light emission from fireflies. It was found that ATP is required for light emission.
