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. (689 aa)    
Predicted Functional Partners:
AHA_1671
Polyphosphate kinase 2; Identified by match to protein family HMM PF03976.
 
  
 0.986
AHA_2830
Exopolyphosphatase; Identified by match to protein family HMM PF02541; Belongs to the GppA/Ppx family.
 
  
 0.980
ppa
Inorganic pyrophosphatase; Catalyzes the hydrolysis of inorganic pyrophosphate (PPi) forming two phosphate ions.
     
 0.930
AHA_2987
Probable manganese-dependent inorganic pyrophosphatase; Identified by match to protein family HMM PF01368.
     
  0.900
gppA
Guanosine-5'-triphosphate,3'-diphosphate pyrophosphatase; 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.
 
  
 0.893
nadK
Probable inorganic polyphosphate/ATP-NAD kinase (Poly(P)/ATP NAD kinase); Involved in the regulation of the intracellular balance of NAD and NADP, and is a key enzyme in the biosynthesis of NADP. Catalyzes specifically the phosphorylation on 2'-hydroxyl of the adenosine moiety of NAD to yield NADP.
      
 0.695
AHA_0917
Polyphosphate glucokinase; Identified by match to protein family HMM PF00480.
 
   
 0.636
AHA_0745
Conserved hypothetical protein.
  
  
 0.617
AHA_2828
ACT domain protein; Identified by match to protein family HMM PF01842.
       0.612
surE
Acid phosphatase SurE; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
      
 0.610
