Chemi- and bioluminescence: Bioluminescence
2023This chapter give examples of theoretical and computational investigations for a better understanding of bioluminescent systems. In bioluminescent systems, the oxidation of substrate inside a protein leads to a product (a light emitter) in its first excited state. Light is emitted with the radiative relaxation of the light emitter.

Annual Review of Cell and Developmental Biology, 1998
▪ Abstract Bioluminescence has evolved independently many times; thus the responsible genes are unrelated in bacteria, unicellular algae, coelenterates, beetles, fishes, and others. Chemically, all involve exergonic reactions of molecular oxygen with different substrates (luciferins) and enzymes (luciferases), resulting in photons of visible light ...

Journal of Bioluminescence and Chemiluminescence, 1989
AbstractFor analytical purposes bioluminescence can be used in three main ways: 1. luminescence measurement of bioluminescent system components isolated in vitro; 2. determination of luminous organisms' reaction to the in vivo test‐action; 3. measurement of bioluminescence in marine ecological systems.The majority of the reports of this Symposium are ...

Annual Review of Marine Science, 2010
Bioluminescence spans all oceanic dimensions and has evolved many times—from bacteria to fish—to powerfully influence behavioral and ecosystem dynamics. New methods and technology have brought great advances in understanding of the molecular basis of bioluminescence, its physiological control, and its significance in marine communities.

In this chapter, we introduce a relatively new, emerging method for molecular neuromodulation-bioluminescence-optogenetics. Bioluminescence-optogenetics is mediated by luminopsin fusion proteins-light-sensing opsins fused to light-emitting luciferases.

PROTEIN STRUCTURE AND BIOLUMINESCENT SPECTRA FOR FIREFLY BIOLUMINESCENCE
Bioluminescence and Chemiluminescence, 2002AbstractModern theory on general and specific effects of microenvironment on emission spectra was used for explanation of spectral differences for both natural and mutant forms of beetle luciferases, as well as for bioluminescence emitter oxyluciferin in model systems. For the analysis, both authors' and other published data were used.

THE ORIGIN OF BIOLUMINESCENCE*
Photochemistry and Photobiology, 1975Abstract— Primitive luciferases evolved in order to utilize oxygen directly as an electron acceptor at the low oxygen concentrations of the primitive atmosphere. This provided a major selective advantage in the ability to metabolize aromatic molecules and n‐alkanes.

Visualization of Bioluminescence
2003There are an increasing number of specialized instruments that may be used for the purpose of measuring bioluminescence. Table 1 contains a representative list of different luminometers and cameras that are available. These instruments have been used to detect bioluminescence in a number of organisms using either bacterial luciferase (lux; 1, 2) or ...

Overview of Bioluminescence; Examples of Bioluminescent Reactions
2010The term 'luminescenz' was introduced by German physicist Eilhardt Wiedemann in 1888, as meaning "all those phenomena of light which are not solely conditioned by the rise in temperature." This was in contrast to the incandescence or 'hot light' that is emitted by any material heated to the temperatures at which they become 'red hot.' Classification of
