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.

Predicted Functional Partners:
codY
Transcriptional pleiotropic repressor; DNA-binding protein that represses the expression of many genes that are induced as cells make the transition from rapid exponential growth to stationary phase. It is a GTP-binding protein that senses the intracellular GTP concentration as an indicator of nutritional limitations. At low GTP concentration it no longer binds GTP and stop to act as a transcriptional repressor; Belongs to the CodY family.
   
 
 0.968
hprK
HPr(ser-P)kinase/phosphatase; Catalyzes the ATP- as well as the pyrophosphate-dependent phosphorylation of a specific serine residue in HPr, a phosphocarrier protein of the phosphoenolpyruvate-dependent sugar phosphotransferase system (PTS). HprK/P also catalyzes the pyrophosphate-producing, inorganic phosphate-dependent dephosphorylation (phosphorolysis) of seryl-phosphorylated HPr (P-Ser-HPr). The two antagonistic activities of HprK/P are regulated by several intracellular metabolites, which change their concentration in response to the absence or presence of rapidly metabolisable ca [...]
      
 0.911
ptsH
Histidine-containing phosphocarrier protein of the PTS.
  
 
 0.784
amy
Alpha-amylase precursor; Belongs to the glycosyl hydrolase 13 family.
  
  
 0.711
purR
Activator of purine biosynthetic genes; Controls the transcription of the pur operon for purine biosynthetic genes.
  
  
 0.691
fruR
Transcriptional repressor of the fructose operon.
  
   
 0.675
ldh
L-lactate dehydrogenase; Catalyzes the conversion of lactate to pyruvate. Belongs to the LDH/MDH superfamily. LDH family.
    
 
 0.669
pfl
Pyruvate formate-lyase.
   
  
 0.668
spxB
Pyruvate oxidase; Belongs to the TPP enzyme family.
   
  
 0.666
glnR
Transcriptional repressor of the glutamine synthetase gene.
      
 0.660
