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 pyrophosphatase; Catalyzes the hydrolysis of inorganic pyrophosphate (PPi) forming two phosphate ions. (162 aa)    
Predicted Functional Partners:
atpF-2
F-type H+-transporting ATPase subunit delta; Component of the F(0) channel, it forms part of the peripheral stalk, linking F(1) to F(0). This protein is part of the stalk that links CF(0) to CF(1). It either transmits conformational changes from CF(0) to CF(1) or is implicated in proton conduction; Belongs to the ATPase delta chain family.
  
 
 0.981
atpF
F-type H+-transporting ATPase 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.
   
 
 0.938
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.
     
 0.932
atpE
ATP synthase F0 subcomplex C subunit; 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.
   
 
 0.928
atpA
ATP synthase F1 subcomplex alpha subunit; Produces ATP from ADP in the presence of a proton gradient across the membrane. The alpha chain is a regulatory subunit.
   
 
 0.927
atpG
ATP synthase F1 subcomplex 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.
   
 
 0.924
atpD
ATP synthase F1 subcomplex beta subunit; Produces ATP from ADP in the presence of a proton gradient across the membrane. The catalytic sites are hosted primarily by the beta subunits.
   
 
 0.911
atpB
F-type H+-transporting ATPase subunit a; Key component of the proton channel; it plays a direct role in the translocation of protons across the membrane. Belongs to the ATPase A chain family.
   
 
 0.903
atpC
ATP synthase F1 subcomplex epsilon subunit; Produces ATP from ADP in the presence of a proton gradient across the membrane.
   
 
  0.895
efp
Translation elongation factor P (EF-P); Involved in peptide bond synthesis. Stimulates efficient translation and peptide-bond synthesis on native or reconstituted 70S ribosomes in vitro. Probably functions indirectly by altering the affinity of the ribosome for aminoacyl-tRNA, thus increasing their reactivity as acceptors for peptidyl transferase.
