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:
some 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

emrEMultidrug/betaine/choline efflux transporter emre; Multidrug transporter that expels positively charged hydrophobic drugs across the inner membrane of E.coli., thereby conferring resistance to a wide range of toxic compounds. The drug efflux is coupled to an influx of protons. Is involved in the resistance of E.coli cells to methyl viologen, ethidium bromide and acriflavine. Is also able to transport tetraphenylphosphonium (TPP(+)) and benzalkonium (110 aa)    
Predicted Functional Partners:
mdtJ
Multidrug/spermidine efflux pump membrane subunit mdtj; Catalyzes the excretion of spermidine. Can also confer resistance to deoxycholate and SDS
 
     0.784
nhaA
Na+:h+ antiporter, nhaa family; Na(+)/H(+) antiporter that extrudes sodium in exchange for external protons. Catalyzes the exchange of 2 H(+) per Na(+). Can mediate sodium uptake when a transmembrane pH gradient is applied. Active at alkaline pH. Activity is strongly down-regulated below pH 6.5

map
Methionine aminopeptidase; Removes the N-terminal methionine from nascent proteins. The N-terminal methionine is often cleaved when the second residue in the primary sequence is small and uncharged (Met-Ala-, Cys, Gly, Pro, Ser, Thr, or Val). Requires deformylation of the N(alpha)-formylated initiator methionine before it can be hydrolyzed
      
 0.522
emrB
Mfs transporter, dha2 family, multidrug resistance protein; Part of the tripartite efflux system EmrAB-TolC, which confers resistance to antibiotics such as CCCP, FCCP, 2,4-dinitrophenol and nalidixic acid

rarD
Putative chloramphenical resistance permease; Protein involved in response to drug and chloramphenicol transport
      
 0.507
ybcK
DLP12 prophage; putative recombinase; Uncharacterized protein YbcK; Phage or Prophage Related
   
   0.466
b0540
Pseudogene, DLP12 prophage;Phage or Prophage Related
       0.412
b0541
IS3 transposase B; IS, phage, Tn; Transposon-related functions; extrachromosomal; transposon related
       0.412
sugE
Quaternary ammonium compound-resistance protein suge; Guanidinium ion exporter. Couples guanidinium export to the proton motive force, exchanging one guanidinium ion for two protons . Overexpression leads to resistance to a subset of toxic quaternary ammonium compounds such as cetylpyridinium, cetyldimethylethyl ammonium and cetrimide cations
