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

phoUPhosphate transport system regulatory protein PhoU; Plays a role in the regulation of phosphate uptake. (237 aa)    
Predicted Functional Partners:
pstB
Phosphate ABC transporter ATP-binding protein PstB; 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.
 
  
 0.997
pstA
Protein involved in inorganic phosphate transmembrane transporter activity and phosphate ion transmembrane transport.
 
  
 0.995
pstC
Phosphate ABC transporter permease protein PstC; Part of the binding-protein-dependent transport system for phosphate; probably responsible for the translocation of the substrate across the membrane; Belongs to the binding-protein-dependent transport system permease family. CysTW subfamily.
 
  
 0.936
ANL57983.1
ABC transporter substrate-binding protein.
 
  
 0.922
phoB
Phosphate regulon transcriptional regulatory protein PhoB; Protein involved in two-component response regulator activity, DNA binding, two-component signal transduction system (phosphorelay) and regulation of transcription, DNA-dependent.
  
  
 0.830
phoR
Protein involved in two-component sensor activity, protein histidine kinase activity and two-component signal transduction system (phosphorelay).
 
   
 0.770
ANL58289.1
Protein involved in inorganic phosphate transmembrane transporter activity and phosphate ion transport.
     
 0.572
ppa
Inorganic pyrophosphatase; Catalyzes the hydrolysis of inorganic pyrophosphate (PPi) forming two phosphate ions.
     
 0.561
guaB
Inosine 5'-monophosphate dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
  
  
 0.558
ppk
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.
     
 0.545
