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
ppk1Polyphosphate kinase 1; 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. (693 aa)    
Predicted Functional Partners:
ppx
Exopolyphosphatase; Belongs to the GppA/Ppx family.
 
  
 0.957
ppa
Inorganic pyrophosphatase; Catalyzes the hydrolysis of inorganic pyrophosphate (PPi) forming two phosphate ions.
     
 0.942
gppA
ppx/GppA phosphatase family protein; 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.
 
  
 0.809
speG
Spermidine N(1)-acetyltransferase.
       0.636
purM
purM: phosphoribosylformylglycinamidine cyclo-ligase.
     
 0.518
arcB
Aerobic respiration control sensor protein ArcB.
     
 0.503
purN
Phosphoribosylglycinamide formyltransferase; Catalyzes the transfer of a formyl group from 10- formyltetrahydrofolate to 5-phospho-ribosyl-glycinamide (GAR), producing 5-phospho-ribosyl-N-formylglycinamide (FGAR) and tetrahydrofolate.
       0.494
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.
     
 0.475
mgtE-2
Magnesium transporter; Acts as a magnesium transporter.
     
 0.452
phoR
phoR_proteo: phosphate regulon sensor kinase PhoR.
     
 0.451
