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

ycnKPutative transcriptional regulator (DeoR family); May act as a negative transcriptional regulator of ycnJ in the presence of copper. May use copper as a corepressor. (190 aa)    
Predicted Functional Partners:
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.
  
  
 0.999
ycnI
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.
  
  
 0.998
ycnL
Putative reductase or disulfide isomerase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
  
  
 0.955
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.
      
 0.847
qdoR
Transcriptional regulator; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type r: regulator.
      
 0.830
deoR
Transcriptional regulator; Negative regulator of the dra-nupC-pdp operon. DeoR binds cooperatively to the operator DNA, which consists of a palindrome and a direct repeat sequence located 3' to the palindrome. Belongs to the SorC transcriptional regulatory family.
  
  
 0.779
yobA
Hypothetical protein; Evidence 5: No homology to any previously reported sequences.
   
  
 0.760
ytkA
Putative lipoprotein; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type lp: lipoprotein.
  
  
 0.736
yetL
Putative transcriptional regulator (MarR family); Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pr: putative regulator.
      
 0.686
fruK
Fructose-1-phosphate kinase; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type e: enzyme.
