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

ppxPutative exopolyphosphatase; 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. (499 aa)    
Predicted Functional Partners:
relA
RelA/SpoT family 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.
 
 
 0.927
spoT
RelA/SpoT family 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.
  
 
 0.913
ppk1
Polyphosphate kinase 1; Catalyzes the reversible transfer of the terminal phosphate of ATP to form a long-chain polyphosphate (polyP).
 
  
 0.836
ppk
Polyphosphate kinase; COG: COG0855; Pfam: PF02503; InterPro: IPR003414; overlaps another CDS with the same product name.
 
  
 0.824
EFE96885.1
Hypothetical protein; COG: COG0317.
 
 
 0.616
rhlB
ATP-dependent RNA helicase RhlB; COG: COG0513; Pfam: PF00270; InterPro: IPR014001; overlaps another CDS with the same product name; Belongs to the DEAD box helicase family.
  
    0.538
polA
DNA-directed DNA polymerase; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity; Belongs to the DNA polymerase type-A family.
  
    0.426
