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

acrBMultidrug 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. (1049 aa)    
Predicted Functional Partners:
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.
 0.999
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.
 
 0.999
acrZ
AcrAB-TolC efflux pump accessory protein, membrane-associated; AcrA-AcrB-AcrZ-TolC is a drug efflux protein complex with a broad substrate specificity. This protein binds to AcrB and is required for efflux of some but not all substrates, suggesting it may influence the specificity of drug export.
    
 
 0.993
yajC
SecYEG protein translocase auxillary subunit; The SecYEG-SecDF-YajC-YidC holo-translocon (HTL) protein secretase/insertase is a supercomplex required for protein secretion, insertion of proteins into membranes, and assembly of membrane protein complexes. The SecYEG complex is essential for assembly of a number of proteins and complexes, assembly is facilitated in the presence of the SecDF-YajC-YidC subcomplex.
   
 
 0.984
cusC
Copper/silver efflux system, outer membrane component; Forms pores that allow passive diffusion of cations across the outer membrane. Part of a cation efflux system that mediates resistance to copper and silver. In pathogenic strains it allows the bacteria to invade brain microvascular endothelial cells (BMEC) thus allowing it to cross the blood-brain barrier and cause neonatal meningitis.
 
 0.979
mdtA
Multidrug efflux system, subunit A; The MdtABC tripartite complex confers resistance against novobiocin and deoxycholate. MdtABC requires TolC for its function. Belongs to the membrane fusion protein (MFP) (TC 8.A.1) family.
 0.967
mdtE
Anaerobic multidrug efflux transporter, ArcA-regulated; Part of the tripartite efflux system MdtEF-TolC, which confers resistance to compounds such as rhodamine 6G, erythromycin, doxorubicin, ethidium bromide, TPP, SDS, deoxycholate, crystal violet and benzalkonium; Belongs to the membrane fusion protein (MFP) (TC 8.A.1) family.
 
 0.962
acrE
Cytoplasmic membrane lipoprotein; Part of the tripartite efflux system AcrEF-TolC. Involved in the efflux of indole and organic solvents. Belongs to the membrane fusion protein (MFP) (TC 8.A.1) family.
 0.936
emrK
Multidrug resistance efflux pump membrane fusion protein; Part of the tripartite efflux system EmrYK-TolC, which confers resistance to various drugs.
 
  
 0.911
macA
Macrolide transporter membrane fusion protein (MFP) component; Part of the tripartite efflux system MacAB-TolC. MacA stimulates the ATPase activity of MacB by promoting the closed ATP- bound state of MacB, increases the capacity of MacB to bind macrolides such as erythromycin, and provides a physical link between MacB and TolC. When overexpressed, the system confers resistance against macrolides composed of 14- and 15-membered lactones but no or weak resistance against 16-membered ones. In addition, MacA binds tightly rough-core lipopolysaccharide (R-LPS), suggesting that the system co [...]
