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 uptake regulator, PhoU; Plays a role in the regulation of phosphate uptake. (235 aa)    
Predicted Functional Partners:
pstB
Phosphate ABC transporter ATP-binding protein, PhoT family; 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 ABC transporter membrane protein 2, PhoT family.
 
  
 0.992
PstC
Phosphate ABC transporter membrane protein 1, PhoT family; 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.
 
  
 0.983
SDW42579.1
Phosphate ABC transporter substrate-binding protein, PhoT family.
 
  
 0.945
PhoB
Two-component system, OmpR family, phosphate regulon response regulator PhoB.
 
  
 0.850
SDW51242.1
Uncharacterized conserved protein YaeQ, suppresses RfaH defect.
   
    0.692
SDW42542.1
Two-component system, OmpR family, phosphate regulon sensor histidine kinase PhoR.
 
   
 0.685
SDX26003.1

GltB
Glutamate synthase (NADPH) large subunit.
     
 0.638
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.
