LuxG is a functioning flavin reductase for bacterial luminescence.
The luxG gene is part of the lux operon of marine luminous bacteria. luxG has been proposed to be a flavin reductase that supplies reduced flavin mononucleotide (FMN) for bacterial luminescence. However, this role has never been established because the gene product has not been successfully expressed and characterized. In this study, luxG from Photobacterium leiognathi TH1 was cloned and expres...
متن کاملComplete Genome Sequence of Photobacterium leiognathi Strain JS01
Photobacterium leiognathi is a bioluminescent symbiont of fish of the Leiognathidae family. Here, we present the full-genome sequence of P. leiognathi strain JS01, a strain isolated from a nonluminescent Loligo sp. squid of Singaporean origin. No finished genome sequence of this species is currently publicly available.
متن کاملGenomic polymorphism in symbiotic populations of Photobacterium leiognathi.
Photobacterium leiognathi forms a bioluminescent symbiosis with leiognathid fishes, colonizing the internal light organ of the fish and providing its host with light used in bioluminescence displays. Strains symbiotic with different species of the fish exhibit substantial phenotypic differences in symbiosis and in culture, including differences in 2-D PAGE protein patterns and profiles of indig...
متن کاملA pulse-radiolysis study of the catalytic mechanism of the iron-containing superoxide dismutase from Photobacterium leiognathi.
The mechanism of the enzymic reaction of an iron-containing superoxide dismutase purified from the marine bacterium Photobacterium leiognathi was studied by using pulse radiolysis. Measurements of activity were done with two different preparations of enzyme containing either 1.6 or 1.15 g-atom of iron/mol. In both cases, identical values of the second-order rate constant for reaction between su...
متن کاملRegulation of Bioluminescence in Photobacterium leiognathi Strain KNH6.
UNLABELLED Bacterial bioluminescence is taxonomically restricted to certain proteobacteria, many of which belong to the Vibrionaceae. In the most well-studied cases, pheromone signaling plays a key role in regulation of light production. However, previous reports have indicated that certain Photobacterium strains do not use this regulatory method for controlling luminescence. In this study, we ...
