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. (238 aa)    
Predicted Functional Partners:
pstB
Phosphate transport 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.
 
 
 0.996
pstA
Phosphate transport system permease protein PstA.
 
 
 0.994
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.
 
  
 0.943
pstS
Phosphate ABC transporter, periplasmic phosphate-binding protein PstS; Part of the ABC transporter complex PstSACB involved in phosphate import; Belongs to the PstS family.
 
 
 0.915
phoB
Phosphate regulon transcriptional regulatory protein PhoB.
 
  
 0.803
phoR
Phosphate regulon sensor protein PhoR.
 
   
 0.532
CSIRO_4108
Hypothetical protein.
  
  
 0.508
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.
  
  
 0.496
rpoN
RNA polymerase sigma-54 factor RpoN; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
  
  
 0.478
CSIRO_3317
Signal peptidase I; Belongs to the peptidase S26 family.
  
    0.445
