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

ppkPutative 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. (764 aa)    
Predicted Functional Partners:
gppA
Putative guanosine-5'-triphosphate,3'-diphosphate pyrophosphatase.
 
  
 0.964
GDI3484
Polyphosphate kinase.
 
  
 0.915
ppx
Exopolyphosphatase protein.
 
  
 0.903
ppa
Inorganic pyrophosphatase; Catalyzes the hydrolysis of inorganic pyrophosphate (PPi) forming two phosphate ions.
     
 0.890
purN
Putative trifunctional purine biosynthetic protein adenosine-3; Catalyzes the transfer of a formyl group from 10- formyltetrahydrofolate to 5-phospho-ribosyl-glycinamide (GAR), producing 5-phospho-ribosyl-N-formylglycinamide (FGAR) and tetrahydrofolate.
      0.689
gyrB-2
Putative DNA gyrase subunit B; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state. Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation. Also able to catalyze the interconversion of other topological isomers of dsDNA rings, including catenanes and knotted rings. Type II topoisomerases break and join 2 DNA strands simultaneously in an ATP-dependent manner.
 
   
 0.685
gyrB
Putative DNA gyrase subunit B; Topoisomerase IV is essential for chromosome segregation. It relaxes supercoiled DNA. Performs the decatenation events required during the replication of a circular DNA molecule; Belongs to the type II topoisomerase family. ParE type 1 subfamily.
 
   
 0.683
dnaA
Putative chromosomal replication initiator protein dnaA; Plays an important role in the initiation and regulation of chromosomal replication. Binds to the origin of replication; it binds specifically double-stranded DNA at a 9 bp consensus (dnaA box): 5'- TTATC[CA]A[CA]A-3'. DnaA binds to ATP and to acidic phospholipids. Belongs to the DnaA family.
     
 0.683
nhaA
Putative Na(+)/H(+) antiporter 1; Na(+)/H(+) antiporter that extrudes sodium in exchange for external protons; Belongs to the NhaA Na(+)/H(+) (TC 2.A.33) antiporter family.
      
 0.667
treZ
Putative malto-oligosyltrehalose trehalohydrolase.
      
 0.663
