Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.

luxQATPase; At low cell density, in absence of AI-2 (autoinducer 2), LuxQ has a kinase activity and autophosphorylates on a histidine residue. The phosphoryl group is then transferred to an aspartate residue in the response regulator domain. The phosphoryl group is transferred to LuxU, and ultimately to LuxO. At high cell density, in the presence of AI-2, the kinase activity is inactivated, and the response regulator domain has a phosphatase activity. (859 aa)    
Predicted Functional Partners:
luxP
ABC transporter substrate-binding protein; Binds to the signaling molecule autoinducer 2 (AI-2), a furanosyl borate diester, (3a-methyl-5,6-dihydrofuro- [2,3d][1,3,2]dioxaborole-2,2,6,6a-tetraol). This complex then interacts with the LuxQ sensor protein.

luxU
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.
  
 0.996
luxS
S-ribosylhomocysteinase; Involved in the synthesis of autoinducer 2 (AI-2) which is secreted by bacteria and is used to communicate both the cell density and the metabolic potential of the environment. The regulation of gene expression in response to changes in cell density is called quorum sensing. Catalyzes the transformation of S-ribosylhomocysteine (RHC) to homocysteine (HC) and 4,5-dihydroxy-2,3-pentadione (DPD). Belongs to the LuxS family.

luxO
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).
