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
ppkPolyphosphate kinase; 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. (689 aa)    
Predicted Functional Partners:
ppx
Exopolyphosphatase; Belongs to the GppA/Ppx family.
 
  
 0.961
ppa
Inorganic pyrophosphatase; Catalyzes the hydrolysis of inorganic pyrophosphate (PPi) forming two phosphate ions.
     
 0.931
gppA
Guanosine-5'-triphosphate,3'-diphosphate pyrophosphatase; 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.
 
  
 0.841
arsC_1
Arsenate reductase.
 
      0.678
dsrB
Hypothetical protein.
      
 0.637
ydjM
Inner membrane protein YdjM.
      
 0.636
sacA
Sucrose-6-phosphate hydrolase; Enables the bacterium to metabolize sucrose as a sole carbon source; Belongs to the glycosyl hydrolase 32 family.
      
 0.635
speG_2
Spermidine N(1)-acetyltransferase.
       0.603
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.
  
  
 0.530
mgtE-2
Magnesium transporter MgtE; Acts as a magnesium transporter.
     
 0.486
