ID 1.13.12.5 DE Renilla-luciferin 2-monooxygenase. AN Aequorin. AN Luciferase. AN Renilla-type luciferase. CA Renilla luciferin + O(2) = oxidized Renilla luciferin + CO(2) + light. CC -!- From the soft coral coelenterate Renilla reniformis. CC -!- The luciferin is bound to a luciferin-binding protein (BP-LH2). CC -!- The bioluminescent reaction between the luciferin complex, luciferase CC and oxygen is triggered by calcium ions. CC -!- In vivo, the excited state luciferin--luciferase complex undergoes CC the process of nonradiative energy transfer to an accessory protein, CC Renilla green fluorescent protein, which results in green CC bioluminescence. CC -!- In vitro, Renilla luciferase emits blue light in the absence of any CC green fluorescent protein. //
