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

spxARedox-sensitive regulator enzyme; 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. Negatively affects competence and sporulation. Its degradation by the MecA/ClpXP complex is needed for competence development; Belongs to the ArsC family. Spx subfamily. (131 aa)    
Predicted Functional Partners:
yjbH
Putative thiol management oxidoreductase component; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
  
 
 0.935
rpoA
RNA polymerase (alpha subunit); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
    
 
 0.914
sigA
RNA polymerase major sigma-43 factor (sigma-A); 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; Belongs to the sigma-70 factor family. RpoD/SigA subfamily.
    
   0.900
rpoC
RNA polymerase (beta' subunit); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
    
   0.895
yjbC
Putative thiol oxidation management factor; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
  
  
 0.885
rpoE
RNA polymerase (delta subunit); 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. May function in sigma factor switching. It displaces RNA bound to RNA polymerase in a binary complex; Belongs to the RpoE family.
  
 
 0.884
rpoZ
Omega subunit of RNA polymerase; Promotes RNA polymerase assembly. Latches the N- and C- terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits (By similarity).
 
 
   0.848
rnpZA
Omega 1 subunit of RNA polymerase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type f: factor; Belongs to the UPF0356 family.
  
   0.826
rpoB
RNA polymerase (beta subunit); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
    
   0.800
mecA
Adaptor protein controlling oligomerization of the AAA+ protein ClpC; Enables the recognition and targeting of unfolded and aggregated proteins to the ClpC protease or to other proteins involved in proteolysis. Acts negatively in the development of competence by binding ComK and recruiting it to the ClpCP protease. When overexpressed, inhibits sporulation. Also involved in Spx degradation by ClpC.
