''Lingulodinium polyedrum'', a marine dinoflagellate often responsible for red tide, possesses a unique [[luciferase]] enyzme. When mechanically stimulated, the organism uses this enzyme to produce a blue light, likely for use in quorum sensing. Other luciferase enzymes typically produce green-yellow to red light. Also, while all luciferase enzymes produce light through oxidation of luciferin, the biochemical mechanism by which this is achieved varies. This means that while the result is the same, there is low similarity to bacterial or firefly luciferases. | ''Lingulodinium polyedrum'', a marine dinoflagellate often responsible for red tide, possesses a unique [[luciferase]] enyzme.
