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

Score
spxATranscriptional regulator Spx; Interferes with activator-stimulated transcription by interaction with the RNA polymerase alpha-CTD. May function to globally reduce transcription of genes involved in growth- and development- promoting processes and to increase transcription of genes involved in thiol homeostasis, during periods of extreme stress. Belongs to the ArsC family. Spx subfamily. (131 aa)    
Predicted Functional Partners:
MCCL_0616
GTP pyrophosphokinase homolog.
  
 
 0.939
MCCL_1416
Conserved hypothetical protein; Similar to general stress protein.
 
    0.779
MCCL_0535
Conserved hypothetical protein; Similar to arsenate reductase; Belongs to the ArsC family.
  
   
 0.729
rpoA
DNA-directed RNA polymerase alpha chain; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
    
   0.725
mecA
Conserved hypothetical protein; Enables the recognition and targeting of unfolded and aggregated proteins to the ClpC protease or to other proteins involved in proteolysis.
 
  
 0.706
recU
Recombination protein RecU homolog; Endonuclease that resolves Holliday junction intermediates in genetic recombination. Cleaves mobile four-strand junctions by introducing symmetrical nicks in paired strands. Promotes annealing of linear ssDNA with homologous dsDNA. Required for DNA repair, homologous recombination and chromosome segregation; Belongs to the RecU family.
  
     0.681
sigA
RNA polymerase sigma factor SigA; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the primary sigma factor during exponential growth.
    
   0.668
rpoC
DNA-directed RNA polymerase beta' subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
    
   0.648
rpoE
Probable DNA-directed RNA polymerase delta subunit homolog; Participates in both the initiation and recycling phases of transcription. In the presence of the delta subunit, RNAP displays an increased specificity of transcription, a decreased affinity for nucleic acids, and an increased efficiency of RNA synthesis because of enhanced recycling; Belongs to the RpoE family.
  
 
 0.636
MCCL_0748
Conserved hypothetical protein; Similar to functionally unknown protein.
  
     0.630
