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

ppxExopolyphosphatase protein; Belongs to the GppA/Ppx family. (506 aa)    
Predicted Functional Partners:
ppk
Polyphosphate kinase protein; 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.
  
 0.976
spoT
Guanosine-3'5'-bis 3'-pyrophosphohydrolase protein; In eubacteria ppGpp (guanosine 3'-diphosphate 5-' diphosphate) is a mediator of the stringent response that coordinates a variety of cellular activities in response to changes in nutritional abundance.
  
 
 0.722
nlpC
Putative endopeptidase NlpC protein.
 
     0.622
purN
Phosphoribosylaminoimidazole synthetase protein; 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.
      0.611
metG
Methionine--tRNA ligase protein; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation.
 
  
 0.559
guaB
Inosine-5'-monophosphate dehydrogenase protein; 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. Belongs to the IMPDH/GMPR family.
     
 0.529
phoU
Phosphate-specific transport system accessory protein PhoU; Plays a role in the regulation of phosphate uptake.
 
   
 0.526
ERJ19277.1
PAS sensor diguanylate cyclase protein.
     
 0.500
ERJ18816.1
Two-component system OmpR family phosphate regulon sensor histidine kinase PhoR protein.
     
 0.500
ERJ18893.1
Two-component system chemotaxis family sensor kinase CheA protein.
     
 0.491
