Accepted name: Photinus-luciferin 4-monooxygenase (ATP-hydrolysing)
Reaction: Photinus luciferin + O2 + ATP = oxidized Photinus luciferin + CO2 + AMP + diphosphate +

Glossary: Photinus-luciferin = (S)-4,5-dihydro-2-(6-hydroxy-1,3-benzothiazol-2-yl)thiazole-4-carboxylic acid
Other name(s): firefly luciferase; luciferase (firefly luciferin); Photinus luciferin 4-monooxygenase (adenosine triphosphate-hydrolyzing); firefly luciferin luciferase; Photinus pyralis luciferase
Systematic name: Photinus-luciferin:oxygen 4-oxidoreductase (decarboxylating, ATP-hydrolysing)
Comments: Photinus (firefly) is a bioluminescent insect. The first step in the reaction is the formation of an acid anhydride between the carboxylic group and AMP, with the release of diphosphate. The enzyme may be assayed by measurement of light emission.
