Photobacterium phosphoreum

Genome structure

Photobacterium phosphoreum major lineage is Gammaproteobacteria. It contains a single circular chromosome. The genome size is about 4.0 Mb. It has a G+C content of genomic DNA of 41%. The number of genes are 4576. The coding percent is 84.0%. It can be isolated by using plating methods Microbial Genome Sequencing Project.

P. phosphoreum contains in its genome a lux gene that codes for the enzyme luciferase. It transforms chemical energy into light energy. Luciferase is a heterodimer with alpha and beta subunits. These two subunits are coded by luxA and luxB respectively.
