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

tetBMultifunctional tetracycline-metal/H+ antiporter and Na+(K+)/H+ antiporter; Resistance to tetracycline by an active tetracycline efflux. This is an energy-dependent process that decreases the accumulation of the antibiotic in whole cells. This protein functions as a metal- tetracycline/H(+) antiporter; Belongs to the major facilitator superfamily. TCR/Tet family. (458 aa)    
Predicted Functional Partners:
tetL
Tetracycline resistance leader peptide; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type t: transporter.
  
  
 0.967
yyaO
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.
  
  
 0.848
rpsL
Ribosomal protein S12 (BS12); With S4 and S5 plays an important role in translational accuracy.
      
 0.845
yubD
Putative efflux transporter; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pt: putative transporter.
  
     0.761
dfrA
Dihydrofolate reductase; Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis (By similarity).
    
 
 0.703
gyrA
DNA gyrase (subunit A); A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state. Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation. Also able to catalyze the interconversion of other topological isomers of dsDNA rings, including catenanes and knotted rings. Type II topoisomerases break and join 2 DNA strands simultaneously in an ATP-dependent manner.
   
  
 0.682
yyaR
Putative acetyl-transferase; Involved in resistance to streptothricin, a broad-spectrum antibiotic produced by streptomycetes. Detoxifies streptothricin via acetylation of the beta amino group of the first beta-lysyl moiety of streptothricin; Belongs to the acetyltransferase family. GNAT subfamily.
   
  
 0.576
vmlR
ATP-binding cassette efflux transporter; Recognizes and binds in the vacant E-site of ribosomes stalled by some peptidyltransferase center (PTC)-targeting antibiotics. Makes contact with the PTC and both ribosomal subunits. Induces conformational changes in the P-site, which allows it to dislodge the antibiotic from its PTC binding site. Binds to ribosomes either directly following translation initation or subsequent to E tRNA release during elongation. Involved in resistance to a narrow spectrum of antibiotics (the streptogramin A antibiotic virginiamycin M, the lincosamide antibiotic [...]
   
  
 0.571
penP
Beta-lactamase precursor; This protein is a beta-lactamase with a substrate specificity for penicillins.
      
 0.568
aadK
Aminoglycoside 6-adenylyltransferase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; To E.faecalis AadE.
