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

SpoTGuanosine polyphosphate pyrophosphohydrolases/synthetases; 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. (765 aa)    
Predicted Functional Partners:
PTH_0190
Hypothetical protein; Partial GppA (COG0248), Exopolyphosphatase.
 
 
 0.936
Gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.923
Ndk
Nucleoside diphosphate kinase; Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate; Belongs to the NDK family.
    
 0.918
PykF
Pyruvate kinase; Belongs to the pyruvate kinase family.
   
 
 0.916
Dtd
D-Tyr-tRNAtyr deacylase; An aminoacyl-tRNA editing enzyme that deacylates mischarged D-aminoacyl-tRNAs. Also deacylates mischarged glycyl-tRNA(Ala), protecting cells against glycine mischarging by AlaRS. Acts via tRNA- based rather than protein-based catalysis; rejects L-amino acids rather than detecting D-amino acids in the active site. By recycling D- aminoacyl-tRNA to D-amino acids and free tRNA molecules, this enzyme counteracts the toxicity associated with the formation of D-aminoacyl- tRNA entities in vivo and helps enforce protein L-homochirality. Belongs to the DTD family.
  
    0.907
NrdA
Ribonucleotide reductase, alpha subunit; Catalyzes the reduction of ribonucleotides to deoxyribonucleotides. May function to provide a pool of deoxyribonucleotide precursors for DNA repair during oxygen limitation and/or for immediate growth after restoration of oxygen.
     
 0.904
PTH_2613
Hypothetical signal transduction receptor; Containing COG4252, predicted transmembrane sensor domain and partial CyaA (COG2114), Adenylate cyclase, family 3.
     
 0.901
NrdD
Oxygen-sensitive ribonucleoside-triphosphate reductase.
     
 0.900
NrdD-2
Oxygen-sensitive ribonucleoside-triphosphate reductase.
     
 0.900
RpsF
Ribosomal protein S6; Binds together with S18 to 16S ribosomal RNA.
  
 
 0.892
