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

qseBQuorum sensing DNA-binding response regulator in two-component regulatory system with QseC; Member of a two-component regulatory system QseB/QseC. Activates the flagella regulon by activating transcription of FlhDC. Currently it is not known whether this effect is direct or not. (219 aa)    
Predicted Functional Partners:
qseC
Quorum sensing sensory histidine kinase in two-component regulatory system with QseB; Member of a two-component regulatory system QseB/QseC. Activates the flagella regulon by activating transcription of FlhDC. May activate QseB by phosphorylation.

basS
Sensory histidine kinase in two-component regulatory system with BasR; Member of the two-component regulatory system BasS/BasR Autophosphorylates and activates BasR by phosphorylation.
 
 0.973
glrK
Sensor protein kinase regulating glmY sRNA in two-component system with response regulator GlrR; Member of the two-component regulatory system GlrR/GlrK that up-regulates transcription of the glmY sRNA when cells enter the stationary growth phase. Activates GlrR by phosphorylation.
 
 0.955
glrR
Response regulator regulating glmY sRNA in two-component system with sensor protein GlrK; Member of the two-component regulatory system GlrR/GlrK that up-regulates transcription of the glmY sRNA when cells enter the stationary growth phase. Regulates glmY transcription by binding to three conserved sites in the purL-glmY intergenic region.

phoQ
Sensory histidine kinase in two-component regulatory system with PhoP; Member of the two-component regulatory system PhoP/PhoQ involved in adaptation to low Mg(2+) environments and the control of acid resistance genes. In low periplasmic Mg(2+), PhoQ functions as a membrane-associated protein kinase that undergoes autophosphorylation and subsequently transfers the phosphate to PhoP, resulting in the expression of PhoP-activated genes (PAG) and repression of PhoP- repressed genes (PRG). In high periplasmic Mg(2+), acts as a protein phosphatase that dephosphorylates phospho-PhoP, resulti [...]
 
 
 0.787
cpxA
Sensory histidine kinase in two-component regulatory system with CpxR; Histidine kinase member of the two-component regulatory system CpxA/CpxR which responds to envelope stress response by activating expression of downstream genes including cpxP, degP, dsbA and ppiA. Activates CpxR by phosphorylation; has autokinase, phosphotransferase and (in the presence of Mg(2+) and/or ATP or ADP) phosphatase activity. The kinase activity is inhibited by periplasmic accessory protein CpxP; proteolysis of CpxP relieves inhibition. Involved in several diverse cellular processes, including the functi [...]

cusS
Copper-sensing histidine kinase in two-component regulatory system with CusR; Member of the two-component regulatory system CusS/CusR involved in response to copper and silver. Acts as a copper/silver ion sensor. Activates CusR by phosphorylation.
   
 0.761
yedV
Putative sensory kinase in two-component regulatory system with YedW; Member of a two-component regulatory system HprR/HprS involved in response to hydrogen peroxide. Senses H(2)O(2), maybe via the redox state of the membrane. Activates HprR by phosphorylation. Can also phosphorylate CusR.
   
 0.761
ygiW
Hydrogen peroxide and cadmium resistance periplasmic protein; stress-induced OB-fold protein.
