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
spx3RNA polymerase (RNAP)-binding regulatory protein, arsenate reductase (ArsC) family, Spx subfamily; 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. (132 aa)    
Predicted Functional Partners:
mecA
Negative regulator of competence; Enables the recognition and targeting of unfolded and aggregated proteins to the ClpC protease or to other proteins involved in proteolysis.
  
  
 0.770
lp_2224
Dithiol-disulfide isomerase, DsbA family,FrnE-like subfamily.
  
 
 0.747
recU
Recombinase; 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.

lp_2061
Hypothetical protein.
  
    0.676
rpoA
DNA-directed RNA polymerase, alpha subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
    
 
 0.624
lp_2226
Competence protein/transcription factor,CoiA-like family.
 
   
 0.597
trxH
Thioredoxin H-type.
  
  
 0.582
rpoD
DNA-directed RNA polymerase, sigma factor 42; 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.
   
   0.561
lp_2261
Hypothetical protein, DUF948 family.
