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

dauAAerobic c4-dicarboxylate transporter daua; Responsible for the aerobic transport of succinate from the periplasm to the cytoplasm at acidic pH. Can transport other C4- dicarboxylic acids such as aspartate and fumarate. May also play a role in the regulation of C4-dicarboxylic acid metabolism at pH 7, via regulation of expression and/or activity of DctA. May act as a co- sensor of DcuS (559 aa)    
Predicted Functional Partners:
bcr
Mfs transporter, dha1 family, multidrug resistance protein; Involved in sulfonamide (sulfathiazole) and bicyclomycin resistance . Probable membrane translocase. A transporter able to export peptides. When overexpressed, allows cells deleted for multiple peptidases (pepA, pepB, pepD and pepN) to grow in the presence of dipeptides Ala-Gln or Gly-Tyr which otherwise inhibit growth . Cells overexpressing this protein have decreased intracellular levels of Ala-Gln dipeptide, and in a system that produces the Ala-Gln dipeptide overproduction of this protein increases export of the dipeptide

acpP
Acyl carrier protein (acp); Carrier of the growing fatty acid chain in fatty acid biosynthesis
   
   0.806
yfdY
annotation not available
      
 0.736
dctA
C4-dicarboxylic acid, orotate and citrate transporter; Responsible for the aerobic transport of the dicarboxylates fumarate, L- and D-malate and to a lesser extent succinate, from the periplasm across the inner membrane
  
  
 0.692
glyS
Glycine trna synthetase, beta subunit; Belongs to the class-II aminoacyl-tRNA synthetase family
      
 0.678
cynT
Carbonic anhydrase 1; Reversible hydration of carbon dioxide. Carbon dioxide formed in the bicarbonate-dependent decomposition of cyanate by cyanase (CynS) diffuses out of the cell faster than it would be hydrated to bicarbonate, so the apparent function of this enzyme is to catalyze the hydration of carbon dioxide and thus prevent depletion of cellular bicarbonate
 
 
 0.666
prs
Phosphoribosylpyrophosphate synthase; Involved in the biosynthesis of the central metabolite phospho-alpha-D-ribosyl-1-pyrophosphate (PRPP) via the transfer of pyrophosphoryl group from ATP to 1-hydroxyl of ribose-5-phosphate (Rib- 5-P)
   
 
 0.611
dcuR
Member of the two-component regulatory system DcuR/DcuS. Involved in the C4-dicarboxylate-stimulated regulation of the genes encoding the anaerobic fumarate respiratory system (frdABCD; nuoAN; dcuB; dcuC; sdhCDAB; etc.). Weakly regulates the aerobic C4- dicarboxylate transporter dctA
  
   
 0.575
tfaR
Rac prophage; putative tail fiber assembly protein tfar; Belongs to the tfa family
   
  
 0.529
proS
Prolyl-trna synthetase; Catalyzes the attachment of proline to tRNA(Pro) in a two- step reaction: proline is first activated by ATP to form Pro-AMP and then transferred to the acceptor end of tRNA(Pro). As ProRS can inadvertently accommodate and process non-cognate amino acids such as alanine and cysteine, to avoid such errors it has two additional distinct editing activities against alanine. One activity is designated as 'pretransfer' editing and involves the tRNA(Pro)-independent hydrolysis of activated Ala-AMP. The other activity is designated 'posttransfer' editing and involves dea [...]
