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

ppaXPyrophosphatase PpaX; Pyrophosphate + H2O <=> 2 Orthophosphate. (217 aa)    
Predicted Functional Partners:
ppa-2
Inorganic pyrophosphatase; Catalyzes the hydrolysis of inorganic pyrophosphate (PPi) forming two phosphate ions.
   
 
  0.912
ppa
Inorganic pyrophosphatase (EC:3.6.1.1) (PPase) [1, 2] is the enzyme responsible for the hydrolysis of pyrophosphate (PPi) which is formed principally as the product of the many biosynthetic reactions that utilise ATP.
   
 
  0.912
ppk
Polyphosphate 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.
  
 
  0.901
atpG
ATP synthase gamma chain (ATP synthase F1 sector gamma subunit); Produces ATP from ADP in the presence of a proton gradient across the membrane. The gamma chain is believed to be important in regulating ATPase activity and the flow of protons through the CF(0) complex.
   
 
  0.701
atpD
ATP synthase subunit beta (ATPase subunit beta) (ATP synthase F1 sector subunit beta); Produces ATP from ADP in the presence of a proton gradient across the membrane. The catalytic sites are hosted primarily by the beta subunits; Belongs to the ATPase alpha/beta chains family.
  
 
  0.699
atpH
ATP synthase delta chain; This protein seems to be part of the stalk that links CF(0) to CF(1). It either transmits conformational changes from CF(0) into CF(1) or is implicated in proton conduction [H]. ATP + H2O + H+(In) = ADP + phosphate + H+(Out).
  
 
  0.697
atpF
ATP synthase B chain (F0F1 ATP synthase subunit B); Component of the F(0) channel, it forms part of the peripheral stalk, linking F(1) to F(0); Belongs to the ATPase B chain family.
  
 
  0.696
atpA
ATP synthase subunit alpha (ATPase subunit alpha) (ATP synthase F1 sector subunit alpha); Produces ATP from ADP in the presence of a proton gradient across the membrane. The alpha chain is a regulatory subunit. Belongs to the ATPase alpha/beta chains family.
   
 
  0.668
atpB
ATP synthase A chain (ATPase protein 6) (F1F0-ATPase subunit a); Key component of the proton channel; it plays a direct role in the translocation of protons across the membrane.
   
 
  0.666
atpC
ATP synthase epsilon chain (ATP synthase F1 sector epsilon subunit); Produces ATP from ADP in the presence of a proton gradient across the membrane.
  
 
  0.664
