(Biochem.)
any of several substances found in luminescent organisms
(such as the firefly, Photinus pyralis) which, when

Photinus pyralis
(gcide) | Firefly luciferin \Fire"fly` lu*cif"er*in\, n. (Biochem.)
a type of luciferin produced by the firefly {Photinus
pyralis}.
Note: Its structure has been elucidated, and chemically it is
recognized as
4,5-Dihydro-2-(6-hydroxy-2-benzothiazol-2-yl)-4-thiazolecarboxylic
acid, C11H8N3O2S2. It has found use in a very
sensitive assay for ATP, in which concentrations of ATP
as low as 10^-11 molar can be detected. --[MI11]

[1913 Webster]
Note: The common American species belong to the genera
