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

csoRRepressor of copper utilisation proteins; Copper-sensitive repressor that has a key role in copper homeostasis. Negatively regulates expression of the copZA operon and of ycnJ. In the absence of copper ions, binds with high affinity to the copZA promoter and represses the transcription. In the presence of copper ions, CsoR binds Cu(1+), which significantly decreases its DNA binding affinity and leads to the transcription of the genes. (101 aa)    
Predicted Functional Partners:
copZ
Copper insertion chaperone and transporter component; Chaperone that serves for the intracellular sequestration and transport of Cu(+). Delivers Cu(+) to the copper-transporting ATPase CopA. Functions in E.coli to transfer Cu(+) to CopA missing its first metal-binding domain.
 
  
 0.997
cueR
Copper efflux transcriptional regulator; Transcriptional activator of the copZA operon.
   
  
 0.979
ycnJ
Putative copper import protein; Involved in uptake of extracellular oxidized copper under copper-limiting conditions; In the N-terminal section; belongs to the CopC family.
     
 0.953
czrA
Transcriptional regulator (multiple metal-sensing ArsR-SmtB transcriptional repressors family); Metal-responsive transcriptional regulator that represses transcription of cadA and the czcD-trkA operon by binding specifically to their promoter. Binding of zinc causes the repressor to dissociate from the DNA.
 
  
 0.939
arsR
Transcriptional regulator (ArsR family); Transcriptional repressor for the ars operon.
  
  
 0.923
copB
copper(I)-transporting ATPase; Couples the hydrolysis of ATP with the transport of cadmium, zinc and cobalt out of the cell. Does not seem to transport copper.
 
  
 0.857
ycnK
Putative transcriptional regulator (DeoR family); May act as a negative transcriptional regulator of ycnJ in the presence of copper. May use copper as a corepressor.
      
 0.847
copA
Copper transporter ATPase; Involved in copper export.
  
 0.846
mntR
Transcriptional regulator (DtxR family); Central regulator of manganese homeostasis that regulates the expression of both manganese uptake and efflux systems. In the presence of high levels of manganese, it mediates repression of the manganese uptake systems MntH and MntABCD and activation of the efflux systems MneP and MneS. Binds with high affinity to the regulatory regions of its target genes. The manganese concentration required for activation of efflux is higher than that for repression of uptake ; Belongs to the DtxR/MntR family.
      
 0.704
ycnI
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.
      
 0.680
