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

dctAC4-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; Belongs to the dicarboxylate/amino acid:cation symporter (DAACS) (TC 2.A.23) family. (428 aa)    
Predicted Functional Partners:
dcuS
Sensor histidine kinase DcuS; 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. Activates DcuR by phosphorylation.
 
  
 0.920
dcuB
C4-dicarboxylate transporter, anaerobic; Responsible for the transport of C4-dicarboxylates from the periplasm across the inner membrane; Belongs to the DcuA/DcuB transporter (TC 2.A.13.1) family.
   
  
 0.913
dcuR
Response regulator in two-component regulatory system with DcuS; 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.

 0.828
citT
Citrate/succinate antiporter; Responsible for the uptake of citrate in exchange with the efflux of succinate, fumarate or tartrate. Has a relatively broad specificity for C(4)-dicarboxylates and tricarboxylates ; Belongs to the SLC13A/DASS transporter (TC 2.A.47) family. DIT1 subfamily.
      
 0.819
mglB
Methyl-galactoside transporter subunit; This protein is involved in the active transport of galactose and glucose. It plays a role in the chemotaxis towards the two sugars by interacting with the trg chemoreceptor.
