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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

ppkPolyphosphate 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 (700 aa)    
Predicted Functional Partners:
ppx
Exopolyphosphatase; Unnamed protein product; Belongs to the GppA/Ppx family
 
  
 0.954
ppa
Inorganic pyrophosphatase; Catalyzes the hydrolysis of inorganic pyrophosphate (PPi) forming two phosphate ions
    
 0.947
hppA
K(+)-insensitive pyrophosphate-energized proton pump; Proton pump that utilizes the energy of pyrophosphate hydrolysis as the driving force for proton movement across the membrane. Generates a proton motive force
     
  0.900
phoR
Two-component system sensor protein; Signal transduction histidine kinase
     
 0.740
phoB
Two-component system regulatory protein; Response regulators consisting of a CheY-like receiver domain and a winged-helix DNA-binding domain
     
 0.701
pimA
Glycosyltransferase
       0.588
spp
Uncharacterized protein; Membrane-associated phospholipid phosphatase
       0.554
lon
Lon protease; ATP-dependent serine protease that mediates the selective degradation of mutant and abnormal proteins as well as certain short-lived regulatory proteins. Required for cellular homeostasis and for survival from DNA damage and developmental changes induced by stress. Degrades polypeptides processively to yield small peptide fragments that are 5 to 10 amino acids long. Binds to DNA in a double-stranded, site-specific manner
      
 0.483
phoU
Phosphate-specific transport system accessory protein PhoU; Plays a role in the regulation of phosphate uptake
     
 0.481
metG
Methionine--tRNA ligase; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation
     
 0.475
