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

marBPeriplasmic mar operon regulator; Multiple antibiotic resistance protein; Protein involved in response to drug and xenobiotic metabolic process. (72 aa)    
Predicted Functional Partners:
marA
Multiple antibiotic resistance transcriptional regulator; 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.
  
  
 0.997
marR
Transcriptional repressor of multiple antibiotic resistance; 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.
  
  
 0.990
soxS
Superoxide response regulon transcriptional activator; 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.
   
  
 0.733
rob
Right oriC-binding transcriptional activator, AraC family; Binds to the right arm of the replication origin oriC of the chromosome. Rob binding may influence the formation of the nucleoprotein structure, required for oriC function in the initiation of replication.
      
 0.600
acrA
Multidrug efflux system; AcrA-AcrB-AcrZ-TolC is a drug efflux protein complex with broad substrate specificity that uses the proton motive force to export substrates. This subunit may act as an adapter protein that links AcrB and TolC stably together. It is elongated in shape, being long enough to span the periplasm.
      
 0.529
acrR
Transcriptional repressor; Potential regulator protein for the acrAB genes.
      
 0.523
inaA
Acid-inducible Kdo/WaaP family putative kinase; May be an environmental sensor responsive to several stimuli, including internal pH, proton motive force, temperature, and possibly other unknown factors; Belongs to the protein kinase superfamily. KdkA/RfaP family.
   
  
 0.520
marC
UPF0056 family inner membrane protein.
  
    0.420
