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

citBResponse 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. (226 aa)    
Predicted Functional Partners:
citA
Sensory histidine kinase in two-component regulatory system with CitB; 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.
 
 0.999
citC
Citrate lyase ligase; Acetylation of prosthetic group (2-(5''-phosphoribosyl)-3'- dephosphocoenzyme-A) of the gamma subunit of citrate lyase.
 
   
 0.897
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.
   
 0.894
citD
Citrate lyase, acyl carrier (gamma) subunit; Covalent carrier of the coenzyme of citrate lyase; Belongs to the CitD family.
 
   
 0.764
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.
  
  
 0.707
citE
Citrate lyase, citryl-ACP lyase (beta) subunit; Represents a citryl-ACP lyase.
 
  
 0.666
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.
 
  
 0.638
yehT
Putative response regulator in two-component system withYehU; Member of the two-component regulatory system BtsS/BtsR, which is part of a nutrient-sensing regulatory network composed of BtsS/BtsR, the low-affinity pyruvate signaling system YpdA/YpdB and their respective target proteins, BtsT and YhjX. Responds to depletion of nutrients, specifically serine, and the concomitant presence of extracellular pyruvate. BtsR regulates expression of btsT by binding to its promoter region. Activation of the BtsS/BtsR signaling cascade also suppresses YpdA/YpdB-mediated yhjX induction.
  
   
 0.608
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.
 
  
 0.584
rstA
Response regulator of RstAB two-component system; Member of the two-component regulatory system RstB/RstA.
  
   
 0.582
