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

yqjIPadR family putative transcriptional regulator; Represses the expression of YqjH which is involved in iron homeostasis under excess nickel conditions. Also represses its own expression. (207 aa)    
Predicted Functional Partners:
yqjH
Putative siderophore interacting protein; Plays a role in iron homeostasis under excess nickel conditions; Belongs to the SIP oxidoreductase family.
  
 0.984
feaR
Transcriptional activator for tynA and feaB; Positive regulator of tynA/maoA and feaB/padA, the genes for 2-phenylethylamine catabolism.
   
  
 0.530
cynR
Transcriptional activator of cyn operon; Positively regulates the cynTSX operon, and negatively regulates its own transcription. Binds specifically to the cynR-cynTSX intergenic region.
   
  
 0.526
yqfB
UPF0267 family protein; Belongs to the UPF0267 family.
 
      0.518
xapR
Transcriptional activator of xapAB; Positive regulator required for the expression of xapA and xapB. Binds to the inducer xanthosine.
   
  
 0.511
allS
allD operon transcriptional activator; Positive regulator essential for the expression of allD operon. Binds to the allD promoter; Belongs to the LysR transcriptional regulatory family.
   
  
 0.459
nadR
Trifunctional NAD biosynthesis/regulator protein NadR; This enzyme has three activities: DNA binding, nicotinamide mononucleotide (NMN) adenylyltransferase and ribosylnicotinamide (RN) kinase. The DNA-binding domain binds to the nadB operator sequence in an NAD- and ATP-dependent manner. As NAD levels increase within the cell, the affinity of NadR for the nadB operator regions of nadA, nadB, and pncB increases, repressing the transcription of these genes. The RN kinase activity catalyzes the phosphorylation of RN to form nicotinamide ribonucleotide. The NMN adenylyltransferase activity [...]
  
  
 0.457
murR
Repressor for murPQ, MurNAc 6-P inducible; Represses the expression of the murPQ operon involved in the uptake and degradation of N-acetylmuramic acid (MurNAc). Binds to two adjacent inverted repeats within the operator region. MurNAc 6- phosphate, the substrate of MurQ, is the specific inducer that weakens binding of MurR to the operator. Also represses its own transcription.
  
   
 0.418
rbbA
Ribosome-associated ATPase: ATP-binding protein/ATP-binding membrane protein; Exhibits an intrinsic ATPase activity that is stimulated by both 70S ribosomes and 30S ribosomal subunits. Could be involved in protein-chain elongation and in release of deacyl-tRNA from ribosomes after peptide bond synthesis. Stimulates the synthesis of polyphenylalanine in vitro; In the C-terminal section; belongs to the ABC-2 integral membrane protein family.
  
  
 0.417
betI
Choline-inducible betIBA-betT divergent operon transcriptional repressor; Repressor involved in the biosynthesis of the osmoprotectant glycine betaine. It represses transcription of the choline transporter BetT and the genes of BetAB involved in the synthesis of glycine betaine.
