Most existing bioluminescence imaging methods can only visualize the location of engineered bacteria in vivo, generally precluding the imaging of natural bacteria.

Quorum sensing is a density-dependent mechanism using chemical signal molecules termed autoinducers to regulate diverse biological processes in bacteria, including bioluminescence. However, the correlation between growth and light emission of two typical

Borrowed proteins in bacterial bioluminescence. [PDF]
A library of Photobacterium phosphoreum DNA was screened in lambda 2001 for the lumazine protein gene, using two degenerate 17-mer oligonucleotide probes that were deduced from a partial protein primary sequence. The lumazine protein gene was localized to a 3.4-kilobase BamHI/EcoRI fragment in one clone.

Increased Autonomous Bioluminescence Emission from Mammalian Cells by Enhanced Cofactor Synthesis
The bacterial bioluminescence system has been successfully implemented in mammalian cell lines, enabling the substrate-free luminescence imaging of living cells. One of the major limitations of the system is its comparatively low brightness.

Expression of the lux genes in Streptococcus pneumoniae modulates pilus expression and virulence. [PDF]
Bioluminescence has been harnessed for use in bacterial reporter systems and for in vivo imaging of infection in animal models. Strain Xen35, a bioluminescent derivative of Streptococcus pneumoniae serotype 4 strain TIGR4 was previously constructed for ...

Luciferins Under Construction: A Review of Known Biosynthetic Pathways
Bioluminescence, or the ability of a living organism to generate visible light, occurs as a result of biochemical reaction where enzyme, known as a luciferase, catalyzes the oxidation of a small-molecule substrate, known as luciferin.

Catabolite Repression of Bacterial Bioluminescence: Functional Implications [PDF]
The synthesis of the bioluminescent system of the marine luminous bacterium Photobacterium fischeri (strain MAV) is subject to both transient and catabolite repression by glucose, and this repression can be reversed by adenosine 3′:5′-cyclic monophosphate. Catabolite repression is a mechanism that characteristically

The Sensitized Bioluminescence Mechanism of Bacterial Luciferase [PDF]
AbstractAfter more than one‐half century of investigations, the mechanism of bioluminescence from the FMNH2 assisted oxygen oxidation of an aliphatic aldehyde on bacterial luciferase continues to resist elucidation. There are many types of luciferase from species of bioluminescent bacteria originating from both marine and terrestrial habitats.
