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.

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. (701 aa)    
Predicted Functional Partners:
ppx
Exopolyphosphatase; Degradation of inorganic polyphosphates (polyP). Releases orthophosphate processively from the ends of the polyP chain.
 
  
 0.978
VC_0728
Conserved hypothetical protein; Identified by Glimmer2; putative.
 
  
 0.960
ppa
Inorganic pyrophosphatase; Catalyzes the hydrolysis of inorganic pyrophosphate (PPi) forming two phosphate ions.
  
  
 0.944
VC_1687
Conserved hypothetical protein; Identified by Glimmer2; putative.
     
  0.900
VC_0725
Phosphate ABC transporter, permease protein; Similar to PID:633994 PID:1369911; identified by sequence similarity; putative.
     
 0.783
pstB1
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.
     
 0.779
VC_0727
Phosphate transport system regulatory protein PhoU; Plays a role in the regulation of phosphate uptake.
     
 0.771
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.
 
  
 0.762
VC_0724
Phosphate ABC transporter, permease protein; Similar to PID:633992; identified by sequence similarity; putative.
     
 0.733
rpmI
Ribosomal protein L35; Similar to GP:3095163; identified by sequence similarity; putative; Belongs to the bacterial ribosomal protein bL35 family.
