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

ppa-2Inorganic pyrophosphatase; Catalyzes the hydrolysis of inorganic pyrophosphate (PPi) forming two phosphate ions. (185 aa)    
Predicted Functional Partners:
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.
     
 0.953
ppaX
Pyrophosphatase PpaX; Pyrophosphate + H2O <=> 2 Orthophosphate.
   
 
  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.

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.
   
 
 0.806
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).
   
 
 0.790
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.
   
 
 0.762
atpE
ATP synthase C chain (F1F0-ATPase 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.
   
 
 0.761
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.
   
 
 0.733
efp
Elongation factor 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.
   
  
 0.727
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.
