STRINGSTRING
STRING protein interaction network
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.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

luxUPhosphorelay 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. (113 aa)    
Predicted Functional Partners:
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.

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).
  
 0.971
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.
