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.

Score
ppkRNA degradosome 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. (689 aa)    
Predicted Functional Partners:
ppx
Exopolyphosphatase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the GppA/Ppx family.
 
  
 0.940
ppa
Inorganic pyrophosphatase; Catalyzes the hydrolysis of inorganic pyrophosphate (PPi) forming two phosphate ions.
     
 0.939
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.
 
  
 0.761
APG50191.1
Magnesium transporter; Acts as a magnesium transporter.
     
 0.464
speG_1
Spermidine acetyltransferase; Catalyzes the formation of N(1)- and N(8)-acetylspermidine from spermidine; Derived by automated computational analysis using gene prediction method: Protein Homology.
       0.453
phoU
Phosphate transport system regulatory protein PhoU; Part of the phosphate (Pho) regulon, which plays a key role in phosphate homeostasis. PhoU is essential for the repression of the Pho regulon at high phosphate conditions.
     
 0.437
pstB
Phosphate ABC transporter ATP-binding protein; Part of the ABC transporter complex PstSACB involved in phosphate import. Responsible for energy coupling to the transport system; Belongs to the ABC transporter superfamily. Phosphate importer (TC 3.A.1.7) family.
