GTPase HflX; Involved in modulation of proteins HflK and HflC; part of the hflA locus (high frequency of lysogenization) which governs the lysis-lysogeny decision of bacteriophage lambda by controlling stability of the phage cII protein; Derived by automated computational analysis using gene prediction method: Protein Homology.

RNA polymerase-binding transcription factor; Derived by automated computational analysis using gene prediction method: Protein Homology.

tRNA dimethylallyltransferase; Catalyzes the transfer of a dimethylallyl group onto the adenine at position 37 in tRNAs that read codons beginning with uridine, leading to the formation of N6-(dimethylallyl)adenosine (i(6)A); Belongs to the IPP transferase family.

AAA family ATPase; Acts negatively to control the expression of luminescence. At low cell density, LuxO is phosphorylated, and together with sigma-54, causes repression of the luxCDABEGH operon. This repression could be indirect, LuxO could activate a negative regulator of luminescence. At high cell density, LuxO is dephosphorylated and inactive, therefore the luxCDABEGH operon is not repressed and light is emitted. LuxO and sigma-54 have also a role in activating the production of siderophore and in regulating the rugose colony morphology phenotype (By similarity).

Phosphorelay protein LuxU; Phosphorelay protein which receives sensory signals from LuxN and LuxP and transmits them to LuxO, at low cell density. LuxN and LuxP transfer a phosphoryl group to LuxU on His-58 and this phosphoryl group is further transferred to LuxO. At high cell density, as LuxU could function to establish an equilibrium between the aspartyl-phosphate of LuxN and the aspartyl-phosphate of LuxO, LuxU transfers phosphate from LuxO to LuxN (and probably LuxP) and finally phosphate is drained from the system.

Exodeoxyribonuclease III; Derived by automated computational analysis using gene prediction method: Protein Homology.

PTS sugar transporter; Derived by automated computational analysis using gene prediction method: Protein Homology.

LuxR family transcriptional regulator; Regulatory protein of bacterial bioluminescence. It probably binds the autoinducer molecule and potentiates the transcription of the bioluminescence operon.

ATP-dependent Clp protease ATP-binding subunit ClpX; ATP-dependent specificity component of the Clp protease. It directs the protease to specific substrates. Can perform chaperone functions in the absence of ClpP.
