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

copBcopper(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. (702 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.
 
 
 0.983
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.
     
 0.888
csoR
Repressor 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.
 
  
 0.857
czcD
Potassium/proton-divalent cation antiporter; Involved in divalent cation and potassium homeostasis in the cell. Catalyzes the active efflux of zinc, cadmium and cobalt, in exchange for potassium and H(+) ions.
  
  
 0.836
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.
 
  
 0.833
copA
Copper transporter ATPase; Involved in copper export.
 
 
0.822
yrdP
Putative oxidoreductase; Involved in potassium and divalent cation transport. Enhances the transport activity of the cation/potassium transporter CzcD.
  
  
 0.684
arsR
Transcriptional regulator (ArsR family); Transcriptional repressor for the ars operon.
 
  
 0.564
bdbD
Thiol-disulfide oxidoreductase; Required for the stabilization, possibly via formation of a disulfide bond, of the obligatory competence protein ComGC. May be required for the stability of secreted proteins with disulfide bonds. Not required for sporulation.
   
 
 0.561
bdbC
Thiol-disulfide oxidoreductase; Required for the stabilization, possibly via formation of a disulfide bond, of the obligatory competence protein ComGC. Not normally required for production of the secreted lantibiotic sublancin 168, although it can partially substitute for BdbB when the latter is absent. It may also be required for the stability of other secreted proteins. Not required for sporulation; Belongs to the DsbB family. BdbC subfamily.
