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.

czcDPotassium/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. (311 aa)    
Predicted Functional Partners:
yrdP
Putative oxidoreductase; Involved in potassium and divalent cation transport. Enhances the transport activity of the cation/potassium transporter CzcD.
  
    0.911
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.
  
  
 0.848
ywrK
Putative Na+/H+ antiporter; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pt: putative transporter.
     
 0.750
yfmP
Transcriptional regulator (MerR family) of metal efflux transporter expression; Repressor of the yfmOP operon. A mutation in yfmP leads to overexpression of yfmO, probably causing a decrease in cellular copper that is eventually responsible for a reduced copper induction of copZA.
 
  
 0.694
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.
     
 0.685
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.
  
  
 0.629
ynbB
Putative C-S lyase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
      
 0.591
cueR
Copper efflux transcriptional regulator; Transcriptional activator of the copZA operon.
 
  
 0.505
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.
     
 0.498
copA
Copper transporter ATPase; Involved in copper export.
     
 0.460
