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

ppaInorganic pyrophosphatasee; Catalyzes the hydrolysis of inorganic pyrophosphate (PPi) forming two phosphate ions. (184 aa)    
Predicted Functional Partners:
atpH
ATP synthase delta chain; F(1)F(0) ATP synthase produces ATP from ADP in the presence of a proton or sodium gradient. F-type ATPases consist of two structural domains, F(1) containing the extramembraneous catalytic core and F(0) containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. During catalysis, ATP synthesis in the catalytic domain of F(1) is coupled via a rotary mechanism of the central stalk subunits to proton translocation.
   
 
 0.935
atpG
ATP synthase B' chain; Component of the F(0) channel, it forms part of the peripheral stalk, linking F(1) to F(0). The b'-subunit is a diverged and duplicated form of b found in plants and photosynthetic bacteria. Belongs to the ATPase B chain family.
   
 
 0.932
atpF
ATP synthase B chain; 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.
   
 
 0.932
atpE
ATP synthase C chain; F(1)F(0) ATP synthase produces ATP from ADP in the presence of a proton or sodium gradient. F-type ATPases consist of two structural domains, F(1) containing the extramembraneous catalytic core and F(0) containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. During catalysis, ATP synthesis in the catalytic domain of F(1) is coupled via a rotary mechanism of the central stalk subunits to proton translocation.
   
 
 0.929
atpG-2
ATP synthase gamma chain; 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.
   
 
 0.927
atpA
ATP synthase alpha chain; Produces ATP from ADP in the presence of a proton gradient across the membrane. The alpha chain is a regulatory subunit.
   
 
 0.924
ppa-2
Inorganic pyrophosphatasee; Catalyzes the hydrolysis of inorganic pyrophosphate (PPi) forming two phosphate ions.
  
  
 
0.920
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.
     
 0.918
atpD
ATP synthase beta chain; Produces ATP from ADP in the presence of a proton gradient across the membrane. The catalytic sites are hosted primarily by the beta subunits.
   
 
 0.916
atpC
ATP synthase epsilon chain; Produces ATP from ADP in the presence of a proton gradient across the membrane.
   
 
  0.911
