LuxG

LuxG derives from Photorhabdus like Vibrio natriegens.It codes the protein coding FMN reductase, providing substrate FMNH2 for luciferases[1].

The fundamental enzymes required for bacterial luminescence are encoded by a single operon, luxCDABE, which is found in all species of luminous bacteria.LuxCDABE operon encodes both luciferase (a heterodimer of LuxA and LuxB) and enzymes required for the production of its substrate tetradecanal (LuxC, LuxD and LuxE).LuxA and LuxB encode the two subunits of the bacterial luciferase, while the products of LuxC, LuxD and LuxE synthesise the substrate for the light emitting reaction, tetradecanal.

Usage and Biology

In our luminescence circuit,LuxG is controlled by Pompc,which accecpts osmotic regulation.In case of high osmolarity in the medium, the protein kinase EnvZ, located in the cytoplasmic membrane,phosphorylates the transcription factor OmpR.Phosphorylated OmpR binds the ompC promoter and activates the transcription.
