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

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. (696 aa)    
Predicted Functional Partners:
ALO41002.1
Exopolyphosphatase; Pfam:pfam02541 Ppx/GppA phosphatase family; Belongs to the GppA/Ppx family.
 
 
 0.989
ALO42204.1
Pfam:pfam03976 Polyphosphate kinase 2 (PPK2).
 
  
 0.958
ALO43446.1
Manganese-dependent inorganic pyrophosphatase; Pfam:pfam02833 DHHA2 domain.
     
  0.900
ALO41004.1
Glycine cleavage system protein R; Pfam:pfam13740 ACT domain.
       0.802
gppA
Guanosine pentaphosphate phosphohydrolase; Catalyzes the conversion of pppGpp to ppGpp. Guanosine pentaphosphate (pppGpp) is a cytoplasmic signaling molecule which together with ppGpp controls the 'stringent response', an adaptive process that allows bacteria to respond to amino acid starvation, resulting in the coordinated regulation of numerous cellular activities.

 0.678
pstB
Phosphate import ATP-binding protein PstB; Part of the ABC transporter complex PstSACB involved in phosphate import. Responsible for energy coupling to the transport system; Belongs to the ABC transporter superfamily. Phosphate importer (TC 3.A.1.7) family.
     
 0.596
phoU
Phosphate-specific transport system accessory protein PhoU; Plays a role in the regulation of phosphate uptake.
     
 0.584
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity; Belongs to the DNA polymerase type-A family.
  
  
 0.521
ALO41010.1
Pfam:pfam01384 Phosphate transporter family.
