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

acrRSimilar to E. coli acrAB operon repressor (AAC73566.1); Blastp hit to AAC73566.1 (215 aa), 87% identity in aa 1 - 214. (217 aa)    
Predicted Functional Partners:
acrA
Similar to E. coli acridine efflux pump (AAC73565.1); Blastp hit to AAC73565.1 (397 aa), 91% identity in aa 1 - 397; Belongs to the membrane fusion protein (MFP) (TC 8.A.1) family.
  
  
 0.971
marA
AraC/XylS family transcriptional activator of defense systems; May be a transcriptional activator of genes involved in the multiple antibiotic resistance (Mar) phenotype. It can also activate genes such as sodA, zwf and micF.
  
  
 0.956
acrB
Similar to E. coli acridine efflux pump (AAC73564.1); Blastp hit to AAC73564.1 (1049 aa), 94% identity in aa 1 - 1048.
     
 0.949
marR
Transcriptional repressor of marRAB operon; Repressor of the marRAB operon which is involved in the activation of both antibiotic resistance and oxidative stress genes. Binds to the marO operator/promoter site.
   
  
 0.939
soxS
Transcriptional activator of superoxide response regulon; Transcriptional activator of the superoxide response regulon of E.coli that includes at least 10 genes such as sodA, nfo, zwf and micF. Binds the DNA sequence 5'-GCACN(7)CAA-3'. It also facilitates the subsequent binding of RNA polymerase to the micF and the nfo promoters (By similarity).
      
 0.938
tolC
Outer membrane channel; Specific tolerance to colicin E1; segregation of daughter chromosomes; role in organic solvent tolerance; similar to E. coli outer membrane channel; specific tolerance to colicin E1; segregation of daughter chromosomes (AAC76071.1); Blastp hit to AAC76071.1 (495 aa), 89% identity in aa 1 - 495.
     
 0.902
gyrA
DNA gyrase, subunit A; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state, and also catalyzes the interconversion of other topological isomers of double-stranded DNA rings, including catenanes and knotted rings. Replenishes negative supercoiling downstream of highly transcribed genes to help control overall chromosomal supercoiling density. E.coli makes 15% more negative supercoils in pBR322 plasmid DNA than S.typhimurium; the S.typhimurium GyrB s [...]

soxR
Redox-sensing transcriptional activator SoxR; Activates the transcription of the soxS gene which itself controls the superoxide response regulon. SoxR contains a 2Fe-2S iron- sulfur cluster that may act as a redox sensor system that recognizes superoxide. The variable redox state of the Fe-S cluster is employed in vivo to modulate the transcriptional activity of SoxR in response to specific types of oxidative stress (By similarity).
      
 0.893
acrF
RND family multidrug transport protein; Similar to E. coli integral transmembrane protein; acridine resistance (AAC76298.1); Blastp hit to AAC76298.1 (1034 aa), 22% identity in aa 1 - 506; acriflavin resistance protein F.
     
 0.892
acrD
RND family aminoglycoside/multidrug efflux pump; Similar to E. coli sensitivity to acriflavine, integral membrane protein, possible efflux pump (AAC75523.1); Blastp hit to AAC75523.1 (1037 aa), 94% identity in aa 1 - 1037.
