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

ppaEsterase; Catalyzes the hydrolysis of inorganic pyrophosphate (PPi) forming two phosphate ions. (162 aa)    
Predicted Functional Partners:
atpH
F0F1 ATP synthase subunit B/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.
  
 
 0.949
atpF
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.
   
 
 0.821
atpG
F0F1 ATP synthase subunit gamma; 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.
  
 
 0.794
atpE
ATP synthase F0 subunit C; 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.
   
 
 0.792
ppk
RNA degradosome 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.
     
 0.785
atpA
F0F1 ATP synthase subunit alpha; Produces ATP from ADP in the presence of a proton gradient across the membrane. The alpha chain is a regulatory subunit.
   
 
 0.779
atpD
F0F1 ATP synthase 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.
   
 
 0.771
atpB
F0F1 ATP synthase 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.
   
 
 0.746
atpC
F0F1 ATP synthase subunit epsilon; Produces ATP from ADP in the presence of a proton gradient across the membrane.
   
 
  0.743
ORA75103.1
Polyphosphate kinase 2; Derived by automated computational analysis using gene prediction method: Protein Homology.
