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

Predicted Functional Partners:
atpB
ATP synthase (subunit a, component F0); Key component of the proton channel; it plays a direct role in the translocation of protons across the membrane.
  
 
 0.924
atpE
ATP synthase (subunit c, component F0); 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.
  
 
 0.920
atpH
ATP synthase (subunit delta, component F1); 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; Belongs to the ATPase delta chain family.
   
 
 0.913
atpC
ATP synthase (subunit epsilon, F1 subunit); Produces ATP from ADP in the presence of a proton gradient across the membrane.
   
 
 0.910
atpG
ATP synthase (subunit gamma, component F1); 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.
     
 0.910
atpA
ATP synthase (subunit alpha, component F1); 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.
   
 
 0.910
atpD
ATP synthase (subunit beta, component F1); 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.
   
 
 0.907
atpF
ATP synthase (subunit b, component F0); 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.
   
 
 0.905
ppaX
P-Ser-HPr phosphatase; Hydrolyzes pyrophosphate formed during P-Ser-HPr dephosphorylation by HPrK/P. Might play a role in controlling the intracellular pyrophosphate pool; Belongs to the HAD-like hydrolase superfamily. PpaX family.
   
 
  0.902
guaB
Inosine-monophosphate dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth.
