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
Your Input:
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)
luxNHybrid sensor histidine kinase/response regulator; At low cell density, in the absence of AI-1 (autoinducer 1), LuxN has a kinase activity and autophosphorylates on His-471. The phosphoryl group is then transferred on Asp-771 of the response regulator domain. The phosphoryl group is transferred to LuxU, and ultimately to LuxO. At high cell density, in the presence of AI-1, the kinase activity is inactivated, and the response regulator domain has a phosphatase activity. LuxN phosphatase acts on itself. As LuxU could function to establish an equilibrium between the aspartyl-phosphate of [...] (849 aa)
luxRLuxR family transcriptional regulator; Regulatory protein of bacterial bioluminescence. It probably binds the autoinducer molecule and potentiates the transcription of the bioluminescence operon. (204 aa)
luxSS-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. (172 aa)
hfqRNA chaperone Hfq; RNA chaperone that binds small regulatory RNA (sRNAs) and mRNAs to facilitate mRNA translational regulation in response to envelope stress, environmental stress and changes in metabolite concentrations. Also binds with high specificity to tRNAs. Belongs to the Hfq family. (87 aa)
cqsSHybrid sensor histidine kinase/response regulator; Derived by automated computational analysis using gene prediction method: Protein Homology. (681 aa)
luxMAcyl-homoserine-lactone synthase; Derived by automated computational analysis using gene prediction method: Protein Homology. (399 aa)
cqsACAI-1 autoinducer synthase; Derived by automated computational analysis using gene prediction method: Protein Homology. (393 aa)
