Bioluminescence in Renilla is due to the luciferase-catalyzed oxidation of luciferin. Anderson and Cormier have isolated a membrane-bounded, subcellular particle containing luciferase, a luciferin-binding protein with its associated luciferin and a green fluorescent protein all of which are necessary for bioluminescence and its control. When subjected to hypotonic solutions of calcium, these particles produce a flash of green light identical to the in vivo luminescence of Renilla. These particles, identified as the apparent sites of bioluminescence in Renilla, have been termed lumisomes.
