Bacterial luciferase reporters: the Swiss army knife of molecular biology.


PMID 21636983

Abstract

Bioluminescence is a process during which light in the visible spectrum is emitted as a consequence of an enzymatic reaction catalyzed by luciferases. Luciferases have been identified mainly in marine organisms and are used for several biological purposes include camouflage, repulsion, attraction, communication and illumination. Some of the currently known luciferases have become indispensible tools in modern molecular biology and are used for diverse applications such as autoinducer-1 activity assays, promoter test assays in both prokaryotes and eukaryotes, imaging of bacterial infections in live animals, in vivo activity assays genes involved in host response and disease and monitoring of bacterial contaminations of food products. With the present review, the authors intend to give an overview on the currently used bacterial luciferase reporter systems, their methodologies and applications and compare them to other reporter systems.
