Bioluminescence: Bacterial Luciferases
One of the plates of V. phosphoreum we prepared.
Pathway
Bacterial lux operons emit light using five enzymes:
- luxA and luxB form the luciferase part of the system, they emit light using the substrate tetradecanal
- luxC, luxD and luxE are involved in the biosynthesis of tetradecanal from readily available substrates
Bioluminescent species
The Cambridge team is looking into these bacterial luciferases:
- Vibrio fischeri forms symbioses with squid to prevent the squid from casting a shadow on moonlit nights. Due to this their lux proteins are non-functional above 30 degrees
- Vibrio (formerly Photobacterium) phosphoreum emits a very blue light, perhaps partly through its use of lumazine
