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.

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. (686 aa)    
Predicted Functional Partners:
ADO48596.1
PFAM: protein of unknown function DUF344; KEGG: ent:Ent638_2051 hypothetical protein.
 
  
 0.968
ADO47536.1
KEGG: kpu:KP1_4079 exopolyphosphatase; PFAM: Ppx/GppA phosphatase; Belongs to the GppA/Ppx family.
 
  
 0.961
ppa
Inorganic diphosphatase; Catalyzes the hydrolysis of inorganic pyrophosphate (PPi) forming two phosphate ions.
     
 0.944
gppA
Ppx/GppA phosphatase; 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.
 
  
 0.788
purM
TIGRFAM: phosphoribosylformylglycinamidine cyclo-ligase; KEGG: kva:Kvar_1230 phosphoribosylformylglycinamidine cyclo-ligase; PFAM: AIR synthase related protein domain protein; AIR synthase related protein.
     
 0.565
ADO50662.1
Phosphate uptake regulator, 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.
     
 0.548
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.
       0.520
ADO49664.1
PAS/PAC sensor signal transduction histidine kinase; TIGRFAM: phosphate regulon sensor kinase PhoR; PFAM: ATP-binding region ATPase domain protein; histidine kinase A domain protein; PAS fold domain protein; KEGG: ent:Ent638_0868 phosphate regulon sensor protein; SMART: ATP-binding region ATPase domain protein; histidine kinase A domain protein; PAS domain containing protein.
     
 0.517
