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

citBMember 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
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
Acetylation of prosthetic group (2-(5''-phosphoribosyl)-3'- dephosphocoenzyme-A) of the gamma subunit of citrate lyase
 
   
 0.959
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
  
 0.875
citT
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
 
   
 0.827
citD
Covalent carrier of the coenzyme of citrate lyase
 
   
 0.800
citX
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.
 
   
 0.791
citE
Represents a citryl-ACP lyase
 
   
 0.661
citG
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
 
     0.650
narL
This protein activates the expression of the nitrate reductase (narGHJI) and formate dehydrogenase-N (fdnGHI) operons and represses the transcription of the fumarate reductase (frdABCD) operon in response to a nitrate/nitrite induction signal transmitted by either the NarX or NarQ proteins
      
 0.640
citF
Represents a citrate:acetyl-ACP transferase
 
     0.610
