dinoflagellate-luciferin:oxygen 132-oxidoreductase
A luciferase from dinoflagelates such as Gonyaulax polyedra, Lingulodinium polyedrum, Noctiluca scintillans, and Pyrocystis lunula. It is a single protein with three luciferase domains. The luciferin is strongly bound by a luciferin binding protein above a pH of 7.

physiological function
-
in Lingulodinium polyedrum, three components are involved in luminescence: the enzyme luciferase, the substrate luciferin, and a luciferin-binding protein which protects luciferin from autoxidation

dinoflagellate luciferase activity is highest during the early night phase
luciferase activity in cell-free extracts of Gonyaulax polyedm undergoes a cyclic daily change such that activities of extracts made in the middle of the night phase may be 10 times greater than in extracts of day phase cells. The circadian rhythm of luciferase activity is a result of biological clock-controlled synthesis and/or degradation of the luciferase polypeptide

for each luciferase domain (D1, D2, D3) the removal of approximately 50 N-terminal amino acids results in an increase in the ratio of luciferase activity at pH 8.0 relative to that at pH 6.3. At pH 8.0, peptides D1167-486, D2535-897, and D3927-1241, lacking the first 55, 47, and 62 amino acids of their N-termini retain about 40%, 50%, and 70% of the pH 6.3 luciferase activity, respectively

deletion mutants for N-terminal region of domain 3 of the luciferase show above 20% of wild type activity, the activities of C-terminal deleted mutants decrease drastically to below 1% of wild type
