luciferase
lu·cif·er·ase lü-'sif-ə-.rās, -.rāz n an enzyme that catalyzes the oxidation of luciferin

* * *

lu·cif·er·ase (loo-sifґər-ās) trivial name for a variety of monooxygenases that catalyze a reaction producing bioluminescence in certain marine crustaceans, fish, bacteria, and insects [EC 1.13.12.5–8, 1.14.14.3, 1.14.99.21]. The enzyme is a flavoprotein that oxidizes luciferin to an electronically excited compound that emits energy in the form of light. The color of light emitted varies with the organism. The firefly enzyme is a valuable reagent for measurement of ATP concentration.
