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.

Score
cqsAAminotransferase, class II; Required for the synthesis of the quorum-sensing autoinducer CAI-1 ((S)-3-hydroxytridecan-4-one) which probably functions as an intragenus signal; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. (389 aa)    
Predicted Functional Partners:
cqsS
Sensor histidine kinase/response regulator LuxN; Senses the quorum-sensing autoinducer CAI-1 ((S)-3- hydroxytridecan-4-one) which probably functions as an intragenus signal. The sensory signal is then relayed to LuxU and LuxO.
 
 0.988
bioD
Dethiobiotin synthetase; Catalyzes a mechanistically unusual reaction, the ATP- dependent insertion of CO2 between the N7 and N8 nitrogen atoms of 7,8- diaminopelargonic acid (DAPA) to form an ureido ring.
 
  
 0.890
luxS
Autoinducer-2 production protein; 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.
      
 0.842
luxQ
Sensor histidine kinase LuxQ; 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 (By similarity).
  
 0.839
luxO
LuxO repressor protein; Involved in the regulation of different processes depending on the cell density. Acts together with sigma-54 to repress, perhaps indirectly, some genes.
      
 0.816
bioC
Biotin synthesis protein BioC; Converts the free carboxyl group of a malonyl-thioester to its methyl ester by transfer of a methyl group from S-adenosyl-L- methionine (SAM). It allows to synthesize pimeloyl-ACP via the fatty acid synthetic pathway.
 
  
 0.807
luxP
luxP 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 (By similarity).
   
  
 0.806
luxU
Phosphorelay protein; Phosphorelay protein which receives sensory signals from a sensory kinase and transmit them to LuxO. At low cell density, a phosphoryl group is transferred from the sensory kinase, probably on His-57 and this phosphoryl group is further transferred to LuxO.
     
 0.801
bioB
Biotin synthase; Catalyzes the conversion of dethiobiotin (DTB) to biotin by the insertion of a sulfur atom into dethiobiotin via a radical-based mechanism; Belongs to the radical SAM superfamily. Biotin synthase family.
 
  
 0.797
bioA
Adenosylmethionine-8-amino-7-oxononanoate aminotransferase; Catalyzes the transfer of the alpha-amino group from S- adenosyl-L-methionine (SAM) to 7-keto-8-aminopelargonic acid (KAPA) to form 7,8-diaminopelargonic acid (DAPA). It is the only animotransferase known to utilize SAM as an amino donor; Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family. BioA subfamily.
