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

mprATranscriptional repressor of microcin B17 synthesis and multidrug efflux; Negative regulator of the multidrug operon emrAB. (176 aa)    
Predicted Functional Partners:
emrB
Multidrug efflux system protein; Part of the tripartite efflux system EmrAB-TolC, which confers resistance to antibiotics such as CCCP, FCCP, 2,4-dinitrophenol and nalidixic acid.
 
  
 0.951
emrA
Multidrug efflux system; Part of the tripartite efflux system EmrAB-TolC, which confers resistance to antibiotics such as CCCP, FCCP, 2,4-dinitrophenol and nalidixic acid. EmrA is a drug-binding protein that provides a physical link between EmrB and TolC; Belongs to the membrane fusion protein (MFP) (TC 8.A.1) family.
 
  
 0.938
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.
  
  
 0.873
parC
DNA topoisomerase IV, subunit A; Topoisomerase IV is essential for chromosome segregation; it is the principal protein responsible for decatenating newly replicated chromosomes. It relaxes supercoiled DNA. MukB stimulates the relaxation activity of topoisomerase IV and also has a modest effect on decatenation. Belongs to the type II topoisomerase GyrA/ParC subunit family. ParC type 1 subfamily.
   
  
 0.821
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.
   
  
 0.807
tktA
Transketolase 1, thiamine triphosphate-binding; Catalyzes the transfer of a two-carbon ketol group from a ketose donor to an aldose acceptor, via a covalent intermediate with the cofactor thiamine pyrophosphate. Thus, catalyzes the reversible transfer of a two-carbon ketol group from sedoheptulose-7-phosphate to glyceraldehyde-3-phosphate, producing xylulose-5-phosphate and ribose- 5-phosphate.
   
    0.747
glnS
Glutamine tRNA synthetase; Protein involved in tRNA aminoacylation for protein translation.
   
  
 0.740
ygaH
Putative L-valine exporter, norvaline resistance protein.
  
  
 0.734
rpe
D-ribulose-5-phosphate 3-epimerase; Catalyzes the reversible epimerization of D-ribulose 5- phosphate to D-xylulose 5-phosphate.
  
    0.716
yobF
DUF2527 family heat-induced protein.
   
  
 0.704
