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

Score
ppk1Polyphosphate kinase 1; Catalyzes the reversible transfer of the terminal phosphate of ATP to form a long-chain polyphosphate (polyP). Belongs to the polyphosphate kinase 1 (PPK1) family. (693 aa)    
Predicted Functional Partners:
ppx
Exopolyphosphatase; Belongs to the GppA/Ppx family.
 
  
 0.972
ppa
Inorganic pyrophosphatase; Catalyzes the hydrolysis of inorganic pyrophosphate (PPi) forming two phosphate ions.
     
 0.934
gppA
ppx/GppA phosphatase family protein; Catalyzes the conversion of pppGpp to ppGpp. Guanosine pentaphosphate (pppGpp) is a cytoplasmic signaling molecule which together with ppGpp controls the 'stringent response', an adaptive process that allows bacteria to respond to amino acid starvation, resulting in the coordinated regulation of numerous cellular activities.
 
  
 0.835
speG
Spermidine N(1)-acetyltransferase.
       0.634
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity; Belongs to the DNA polymerase type-A family.
 
  
 0.586
hisD
Histidinol dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
  
  
 0.577
purM
purM: phosphoribosylformylglycinamidine cyclo-ligase.
     
 0.517
purN
Phosphoribosylglycinamide formyltransferase; Catalyzes the transfer of a formyl group from 10- formyltetrahydrofolate to 5-phospho-ribosyl-glycinamide (GAR), producing 5-phospho-ribosyl-N-formylglycinamide (FGAR) and tetrahydrofolate.
       0.500
hisC
hisC: histidinol-phosphate transaminase; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. Histidinol-phosphate aminotransferase subfamily.
      
 0.488
etfB_2
Electron transfer flavodomain protein; Required for anaerobic carnitine reduction. May bring reductant to CaiA.
      
 0.475
