The Mechanism of Bacterial Bioluminescence

2018
Bioluminescence is a chemiluminescence in which one of the participants is a protein and where the light emission serves a functional purpose for the organism in which the protein is found. Bioluminescence with bacterial luciferase, henceforth just referred to as luciferase, is obtained in a reaction with FMNH2 and a long-chain aliphatic aldehyde such ...

Fluorescence and bioluminescence of bacterial luciferase intermediates

Biochemistry, 1975
An intermediate in the luciferase-catalyzed bioluminescent oxidation of FMNH2, isolated and purified by chromatography at -20degrees, was postulated to be an oxygenated reduced flavin-luciferase. Maintained and studied at -20 to -30degrees, this material exhibits a relatively weak fluorescence emission peaking about 505 nm when excited at 370 nm.

Effects of potassium halides on bacterial bioluminescence

Journal of Photochemistry and Photobiology B: Biology, 2002
The effects of potassium halides KCl, KBr and KI on NADH:FMN-oxidoreductase-luciferase bioluminescent coupled enzyme system were studied. The influence of salt additions on bioluminescence intensity and bioluminescence light yield was investigated.

Biochemistry and Genetics of Bacterial Bioluminescence

2014
Bacterial light production involves enzymes-luciferase, fatty acid reductase, and flavin reductase-and substrates-reduced flavin mononucleotide and long-chain fatty aldehyde-that are specific to bioluminescence in bacteria. The bacterial genes coding for these enzymes, luxA and luxB for the subunits of luciferase; luxC, luxD, and luxE for the ...

Bioluminescent bacterial imaging in vivo.

Journal of visualized experiments : JoVE, 2013
This video describes the use of whole body bioluminesce imaging (BLI) for the study of bacterial trafficking in live mice, with an emphasis on the use of bacteria in gene and cell therapy for cancer. Bacteria present an attractive class of vector for cancer therapy, possessing a natural ability to grow preferentially within tumors following systemic ...

[13] Bacterial bioluminescence: An overview

1978
Publisher Summary This chapter describes bioluminescent bacteria that occur ubiquitously in the ocean and in some non-marine habitats. These bacteria also occur as symbionts, harbored by their hosts within special light organs. Hosts derive their ability to luminesce from the bacteria.

Sensory Mechanisms Controlling Bacterial Bioluminescence

1999
Abstract : The goal of this project was to explore the sensory mechanisms which control the expression of bioluminescence in the marine bacterium Vibrio harveyi. Genetic methods were used to discover the genes which encode functions for the production of extracellular, chemical signals (autoinducers) and for the synthesis of proteins which mediate the ...
