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

copZCopper 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. (69 aa)    
Predicted Functional Partners:
copA
Copper transporter ATPase; Involved in copper export.
 
 
 0.997
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.
 
  
 0.997
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.
 
 
 0.983
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.
     
 0.944
sodC
Superoxide dismutase (exported lipoprotein); Evidence 1a: Function experimentally demonstrated in the studied strain; Product type lp: lipoprotein.
   
 0.933
cueR
Copper efflux transcriptional regulator; Transcriptional activator of the copZA operon.
  
  
 0.928
zosA
Zn transporter; Couples the hydrolysis of ATP with the transport of zinc into the cell. Plays an important role in protecting cells against oxidative stress. ZosA-mediated zinc transport is required for post- transcriptional control of comK and competence development.
 
 
 0.746
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.
  
  
 0.626
yyaN
Putative transcriptional regulator (MerR family); Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative regulator.
  
  
 0.622
yrkF
Putative rhodanese-related sulfur transferase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme; Belongs to the sulfur carrier protein TusA family.
