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 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. (243 aa)    
Predicted Functional Partners:
pstB
Phosphate transport system permease 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.
 
  
 0.995
pstA
Phosphate transport system permease protein PstA.
 
  
 0.969
pstC
Phosphate transport system 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.
 
  
 0.789
pstS
Phosphate-binding periplasmic protein precursor PstS; Part of the ABC transporter complex PstSACB involved in phosphate import; Belongs to the PstS family.
 
  
 0.714
phoR
Phosphate regulon sensor protein.
 
   
 0.564
parC
Topoisomerase IV subunit A; Topoisomerase IV is essential for chromosome segregation. It relaxes supercoiled DNA. Performs the decatenation events required during the replication of a circular DNA molecule; Belongs to the type II topoisomerase GyrA/ParC subunit family. ParC type 1 subfamily.
   
  
 0.559
plu0219
Unnamed protein product; Highly similar to binding protein component of ABC transporter; Belongs to the bacterial solute-binding protein 3 family.
     
 0.527
rpoN
RNA polymerase sigma-54 factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
 
  
 0.498
phoB
Phosphate regulon transcriptional regulatory protein.
 
  
 0.492
bvgS
Virulence sensor protein BvgS precursor.
     
 0.464
