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

ppaXP-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. (216 aa)    
Predicted Functional Partners:
lgt
Prelipoprotein diacylglycerol transferase; Catalyzes the transfer of the diacylglyceryl group from phosphatidylglycerol to the sulfhydryl group of the N-terminal cysteine of a prolipoprotein, the first step in the formation of mature lipoproteins. Required for spore germination; Belongs to the Lgt family.

hprK
Serine/threonine protein kinase/phosphorylase; Catalyzes the ATP- as well as the pyrophosphate-dependent phosphorylation of 'Ser-45' in HPr, a phosphocarrier protein of the phosphoenolpyruvate-dependent sugar phosphotransferase system (PTS). HprK/P also catalyzes the pyrophosphate-producing, inorganic phosphate- dependent dephosphorylation (phosphorolysis) of seryl-phosphorylated HPr (P-Ser-HPr). The two antagonistic activities of HprK/P are regulated by several intracellular metabolites, which change their concentration in response to the absence or presence of rapidly metabolisable c [...]

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.
  
 
  0.923
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.
  
 
  0.921
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.
  
 
  0.919
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.

yvoF
Putative O-acetyltransferase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme; Belongs to the transferase hexapeptide repeat family.
  
    0.916
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.
  
 
  0.913
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.
  
 
  0.909
atpC
ATP synthase (subunit epsilon, F1 subunit); Produces ATP from ADP in the presence of a proton gradient across the membrane.
