ID 1.13.12.7 DE Photinus-luciferin 4-monooxygenase (ATP-hydrolyzing). AN Firefly luciferase. AN Luciferase. AN Photinus pyralis luciferase. CA Photinus luciferin + O(2) + ATP = oxidized Photinus luciferin + CO(2) + CA AMP + diphosphate + light. CC -!- Photinus (firefly) is a bioluminescent insect. CC -!- The first step in the reaction is the formation of an acid anhydride CC between the carboxylic group and AMP, with the release of CC diphosphate. CC -!- The enzyme may be assayed by measurement of light emission.
