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

acrSacrAB operon transcriptional repressor; Potential regulator protein for the acrEF/envCD genes. (220 aa)    
Predicted Functional Partners:
acrF
Multidrug efflux system protein; Part of the tripartite efflux system AcrEF-TolC. Involved in the efflux of indole and organic solvents. Belongs to the resistance-nodulation-cell division (RND) (TC 2.A.6) family.
  
  
 0.759
yhdJ
DNA adenine methyltransferase, SAM-dependent; Methylates the second adenine of the NsiI recognition sequence (5'-ATGCAT-3').
   
   0.667
acrB
Multidrug efflux system protein; AcrA-AcrB-AcrZ-TolC is a drug efflux protein complex with broad substrate specificity that uses the proton motive force to export substrates.
     
 0.648
mdtP
Outer membrane factor of efflux pump; Could be involved in resistance to puromycin, acriflavine and tetraphenylarsonium chloride.
  
  
 0.643
mdtM
Multidrug efflux system protein; Confers resistance to acriflavine, chloramphenicol, norfloxacin, ethidium bromide and TPP; Belongs to the major facilitator superfamily.
      
 0.624
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.
     
 0.621
yojI
Microcin J25 efflux ABC transporter permease/ATPase; Mediates resistance to the antibacterial peptide microcin J25, when expressed from a multicopy vector. Functions as an efflux pump for microcin J25, with the help of the outer membrane channel TolC.
      
 0.593
tolC
Transport channel; Outer membrane channel, which is required for the function of several efflux systems such as AcrAB-TolC, AcrEF-TolC, EmrAB-TolC and MacAB-TolC. These systems are involved in export of antibiotics and other toxic compounds from the cell. TolC is also involved in import of colicin E1 into the cells.
     
 0.564
emrK
Multidrug resistance efflux pump membrane fusion protein; Part of the tripartite efflux system EmrYK-TolC, which confers resistance to various drugs.
  
  
 0.549
ybcK
DLP12 prophage; putative recombinase.
   
    0.538
