摘要：

A system which emits light upon calcium addition was obtained from the bioluminescent sea pansy Renilla by extracting in EDTA. The activity has properties similar t o photoproteins isolated from other coelenterates, but differs by virtue of being associated with a particulate material. A unitary biochemical scheme in coelenterates is proposed, in which the oxidation of a luciferin is postulated to form a stable protein (enzyme)-bound peroxide intermediate, whose further reaction to form a dioxetane ring is triggered by the Ca++-Protein interaction. The concerted cleavage of the dioxetane ring yields one of the carbonyl fragments in the excited state. © 1969.
