luciferase

(lo͞o-sĭf′ə-rās′, -rāz′)
n.
An enzyme present in the cells of bioluminescent organisms that catalyzes the oxidation of luciferin and ATP, producing light.

luciferase

A mono-oxygenase enzyme (EC 1.13.12.7) that catalyses bioluminescent reactions, using luciferin as a substrate.

luciferase

an oxidizing enzyme that, acting on the bioluminescent substance luciferin, causes luminosity in glow-worms and other insects. see LUMINESCENCE.
