Firefly Bioluminescence (Luciferin Oxidation)

Luciferin + ATP + O2 → Oxyluciferin + AMP + PPi + CO2 + hν

Visão geral

Firefly luciferase catalyzes the ATP-dependent oxidation of luciferin, producing oxyluciferin in an electronically excited state that emits yellow-green light (560 nm). This is the most efficient bioluminescent system known, converting about 88% of chemical energy to light with almost no heat waste.
