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

ccpNNegative regulator of gluconeogenesis; Transcription repressor that binds to the promoter of gapB and pckA genes, preventing their expression. Acts as a regulator for catabolite repression of gluconeogenic genes. (212 aa)    
Predicted Functional Partners:
yqfL
Positive regulator of gluconeogenesis; Bifunctional serine/threonine kinase and phosphorylase involved in the regulation of the pyruvate, phosphate dikinase (PPDK) by catalyzing its phosphorylation/dephosphorylation.
 
  
 0.997
pckA
Phosphoenolpyruvate carboxykinase; Involved in the gluconeogenesis. Catalyzes the conversion of oxaloacetate (OAA) to phosphoenolpyruvate (PEP) through direct phosphoryl transfer between the nucleoside triphosphate and OAA.
      
 0.911
ccpA
Transcriptional regulator (Lacl family); Global transcriptional regulator of carbon catabolite repression (CCR) and carbon catabolite activation (CCA), which ensures optimal energy usage under diverse conditions. Interacts with either P- Ser-HPr or P-Ser-Crh, leading to the formation of a complex that binds to DNA at the catabolite-response elements (cre). Binding to DNA allows activation or repression of many different genes and operons.
   
  
 0.888
gapB
Glyceraldehyde-3-phosphate dehydrogenase; Involved in the gluconeogenesis. Catalyzes the oxidative phosphorylation of glyceraldehyde 3-phosphate (G3P) to 1,3- bisphosphoglycerate (BPG) using the cofactor NADP. The first reaction step involves the formation of a hemiacetal intermediate between G3P and a cysteine residue, and this hemiacetal intermediate is then oxidized to a thioester, with concomitant reduction of NADP to NADPH. The reduced NADPH is then exchanged with the second NADP, and the thioester is attacked by a nucleophilic inorganic phosphate to produce BPG; Belongs to the gl [...]
      
 0.863
ccpC
Transcriptional repressor of citB and citZ; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type r: regulator; Belongs to the LysR transcriptional regulatory family.
  
  
 0.844
cggR
Transcriptional regulator of gapA; In the absence of glucose, represses the transcription of the gapA operon, which encodes five key glycolytic enzymes. Binds specifically to the cggR-gapA promoter region and blocks the progression of the RNA polymerase, leading to the arrest of the transcription; Belongs to the SorC transcriptional regulatory family.
  
  
 0.825
gapA
Glyceraldehyde-3-phosphate dehydrogenase; Involved in the glycolysis. Catalyzes the oxidative phosphorylation of glyceraldehyde 3-phosphate (G3P) to 1,3- bisphosphoglycerate (BPG) using the cofactor NAD. The first reaction step involves the formation of a hemiacetal intermediate between G3P and a cysteine residue, and this hemiacetal intermediate is then oxidized to a thioester, with concomitant reduction of NAD to NADH. The reduced NADH is then exchanged with the second NAD, and the thioester is attacked by a nucleophilic inorganic phosphate to produce BPG.

yqxD
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function; PubMedId: 9387153; Belongs to the UPF0178 family.
  
  
 0.651
glyS
glycyl-tRNA synthetase (beta subunit); Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type e: enzyme.
  
    0.649
dnaG
DNA primase; RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication.
  
 
 0.623
