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. (236 aa)    
Predicted Functional Partners:
pstB
Phosphate ABC transporter, ATP-binding protein; 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.
 
  
 0.998
pstA
Phosphate ABC transporter, permease protein PstA.
 
  
 0.997
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.
 
  
 0.990
pstS
Phosphate ABC transporter, periplasmic phosphate-binding protein.
 
  
 0.985
phoB
Phosphate regulon transcriptional regulatory protein PhoB.
  
  
 0.879
quiP
Acyl-homoserine-lactone acylase.
      
 0.719
phoA
Alkaline phosphatase; Belongs to the alkaline phosphatase family.
  
  
 0.702
ADE85589.1
Sensor histidine kinase.
 
   
 0.601
modA1
Molybdenum ABC transporter, periplasmic molybdenum-binding protein ModA-1.
     
 0.519
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.
