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

dctDC4-dicarboxylate transport transcriptional regulatory protein DctD. (441 aa)    
Predicted Functional Partners:
dctB
C4-dicarboxylate transport sensor protein DctB.
 
 0.989
phnF
Phosphonates metabolism transcriptional regulator PhnF.
   
  
 0.813
prpC
2-methylcitrate synthase; Belongs to the citrate synthase family.
      
 0.721
icd
Isocitrate dehydrogenase (NADP(+)); Belongs to the isocitrate and isopropylmalate dehydrogenases family.
      
 0.720
ntrB
Nitrogen regulation protein NtrB; Member of the two-component regulatory system NtrB/NtrC, which controls expression of the nitrogen-regulated (ntr) genes in response to nitrogen limitation. Under conditions of nitrogen limitation, NtrB autophosphorylates and transfers the phosphoryl group to NtrC. In the presence of nitrogen, acts as a phosphatase that dephosphorylates and inactivates NtrC.
 
 0.653
purQ
Phosphoribosylformylglycinamidine synthase, PurQ component; Part of the phosphoribosylformylglycinamidine synthase complex involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate. The FGAM synthase complex is composed of three subunits. PurQ produces an ammonia molecule by converting glutamine to glutamate. PurL transfers the ammonia molecule to FGAR to form FGAM in an ATP- dependent manner. PurS interacts with PurQ and PurL and is thoug [...]

cheR1
Chemotaxis protein methyltransferase CheR-1.
  
 
 0.616
yaeT
Outer membrane protein assembly factor YaeT; Part of the outer membrane protein assembly complex, which is involved in assembly and insertion of beta-barrel proteins into the outer membrane.
