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

citTCitrate: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 (487 aa)    
Predicted Functional Partners:
citX
Apo-citrate lyase phosphoribosyl-dephospho-coa transferase; Transfers 2-(5''-triphosphoribosyl)-3'-dephosphocoenzyme-A on a serine residue to the apo-acyl carrier protein (gamma chain) of the citrate lyase to yield holo-acyl carrier protein
 
  
 0.964
citG
2-(5''-triphosphoribosyl)-3'-dephosphocoenzyme-A synthase; Catalyzes the formation of 2-(5''-triphosphoribosyl)-3'- dephosphocoenzyme-A, the precursor of the prosthetic group of the holo- acyl carrier protein (gamma chain) of citrate lyase, from ATP and dephospho-CoA
 
  
 0.961
citC
[citrate (pro-3s)-lyase] ligase; Acetylation of prosthetic group (2-(5''-phosphoribosyl)-3'- dephosphocoenzyme-A) of the gamma subunit of citrate lyase
 
  
 0.953
citA
Two-component system, citb family, cit operon sensor histidine kinase cita; Member of the two-component regulatory system DpiA/DpiB, which is essential for expression of citrate-specific fermentation genes and genes involved in plasmid inheritance. Could be involved in response to both the presence of citrate and external redox conditions. Functions as a sensor kinase that phosphorylates DpiA in the presence of citrate
 
   
 0.929
citF
Citrate lyase, citrate-acp transferase (alpha) subunit; Represents a citrate:acetyl-ACP transferase
 
 
 0.915
citD
Citrate lyase subunit gamma (acyl carrier protein); Covalent carrier of the coenzyme of citrate lyase
 
  
 0.908
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
   
  
 0.870
rnk
May act as an anti-Gre factor. Regulates the level of the nucleoside diphosphate kinase Ndk
     
 0.833
dcuC
Anaerobic c4-dicarboxylate transporter dcuc; Responsible for the transport of C4-dicarboxylates during anaerobic growth
      
 0.829
citB
Response regulator in two-component regulatory system with cita; Member of the two-component regulatory system DpiA/DpiB, which is essential for expression of citrate-specific fermentation genes and genes involved in plasmid inheritance. Could be involved in response to both the presence of citrate and external redox conditions. Regulates the transcription of citCDEFXGT, dpiAB, mdh and exuT. Binds specifically to the dpiB-citC intergenic region
