Particulate bioluininescence in dinoflagellates: dissociation and partial reconstitution
Science (New York, N.Y.)
|September 8, 1972
Summary
Bioluminescence was isolated from Pyrodinium bahamense and Pyrocystis lunula using the same methods as Gonyaulax polyedra. Researchers dissociated soluble luciferin and luciferase, finding luciferin can be incorporated into particulate systems.
Area of Science:
- Marine Biology
- Biochemistry
- Biotechnology
Background:
- Bioluminescence, the emission of light by living organisms, is a fascinating phenomenon observed in various marine species.
- Understanding the biochemical mechanisms underlying bioluminescence is crucial for its potential applications.
Purpose of the Study:
- To investigate the isolation and dissociation of bioluminescent components from Pyrodinium bahamense and Pyrocystis lunula.
- To determine if luciferin can be incorporated into particulate bioluminescent systems.
Main Methods:
- Extraction of soluble and particulate bioluminescence using established conditions from Gonyaulax polyedra.
- Dissociation of luciferin and luciferase from the particulate system for all three species.
- Testing the incorporation of luciferin into reacted and unreacted particulate systems.
Main Results:
- Soluble and particulate bioluminescence were successfully isolated from Pyrodinium bahamense and Pyrocystis lunula.
- Luciferin and luciferase were dissociated from the particulate system in all three species.
- Luciferin demonstrated incorporation capabilities into both reacted and unreacted particulate systems.
Conclusions:
- The study successfully isolated and characterized bioluminescent components from additional dinoflagellate species.
- The findings suggest a conserved mechanism for bioluminescence across these species.
- Luciferin's ability to integrate into particulate systems opens avenues for further research and potential biotechnological applications.

01:23Photoluminescence: Fluorescence and Phosphorescence
Photoluminescence is a process where a molecule absorbs light energy and re-emits it in the form of light. This phenomenon occurs when a substance absorbs photons, promoting its electrons to higher energy level excited states, followed by a relaxation process in which the electrons return to their original ground state energy levels and emit light. Photoluminescence is widely observed in various materials, including semiconductors, and organic and inorganic compounds.

01:28Gene Regulation in Microbial Communities: Quorum Sensing
Quorum sensing is a mechanism of bacterial communication that enables coordinated gene expression in response to changes in population density. This facilitates collective behaviors that enhance survival, resource acquisition, and ecological adaptation. This process relies on small signaling molecules called autoinducers that accumulate as bacterial populations grow. When a critical threshold concentration of autoinducers is reached, bacterial cells collectively modify gene expression,...
01:19Protein Dynamics in Living Cells
Different fluorescence-based techniques are used to study the protein dynamics in living cells. These techniques include FRAP, FRET, and PET.
Fluorescent recovery after photobleaching (FRAP) is a fluorescent-protein-based detection technique used to quantify protein movement rates within the cell. This method exposes a small portion of the cell to an intense laser beam. The laser beam causes permanent photobleaching of the fluorophore-tagged proteins in the exposed region. As the bleached...

01:25Deactivation Processes: Jablonski Diagram
Luminescence, the emission of light by a substance that has absorbed energy, is a process that involves the interaction of molecules with light. The energy-level diagram, or Jablonski diagram, is a graphical representation of these interactions, illustrating the various states and transitions a molecule can undergo. In a typical Jablonski diagram, the lowest horizontal line represents the ground-state energy of the molecule, which is usually a singlet state. This state represents the energies...
01:14Photoluminescence: Applications
Photoluminescence offers a wide range of applications due to its inherent sensitivity and selectivity. This technique allows for both direct and indirect analyses of the analyte. Direct quantitative analysis is possible when the analyte exhibits a favorable quantum yield for fluorescence or phosphorescence. However, an indirect analysis may be feasible if the analyte is not fluorescent or phosphorescent, or if the quantum yield is unfavorable. Indirect methods include reacting the analyte with...
