Accepted name: Renilla-luciferin 2-monooxygenase
Reaction: Renilla luciferin + O2 = oxidized Renilla luciferin + CO2 +

Glossary: Renilla luciferin = 2,8-dibenzyl-6-(4-hydroxyphenyl)imidazo[1,2-a]pyrazin-3(7H)-one
Other name(s): Renilla-type luciferase; aequorin; luciferase (Renilla luciferin)
Systematic name: Renilla-luciferin:oxygen 2-oxidoreductase (decarboxylating)
Comments: From the soft coral coelenterate Renilla reniformis. The luciferin is bound to a luciferin-binding protein (BP-LH2). The bioluminescent reaction between the luciferin complex, luciferase and oxygen is triggered by calcium ions. In vivo, the excited state luciferin—luciferase complex undergoes the process of nonradiative energy transfer to an accessory protein, Renilla green fluorescent protein, which results in green bioluminescence. In vitro, Renilla luciferase emits blue light in the absence of any green fluorescent protein.
