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

pstAPhosphate ABC transporter permease; 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. (296 aa)    
Predicted Functional Partners:
pstB
Phosphate ABC transporter ATPase; 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.

pstC
Phosphate ABC transporter permease; 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.
 
 0.999
pstS
Phosphate ABC transporter periplasmic binding protein; Part of the ABC transporter complex PstSACB involved in phosphate import; Belongs to the PstS family.
 
 0.999
phoU
Negative regulator of PhoR/PhoB two-component regulator; Part of the phosphate (Pho) regulon, which plays a key role in phosphate homeostasis. Encoded together with proteins of the phosphate-specific transport (Pst) system in the polycistronic pstSCAB- phoU operon. PhoU is essential for the repression of the Pho regulon at high phosphate conditions. In this role, it may bind, possibly as a chaperone, to PhoR, PhoB or a PhoR-PhoB complex to promote dephosphorylation of phospho-PhoB, or inhibit formation of the PhoR- PhoB transitory complex. Is also part of complex networks important for [...]

phoR
Sensory histidine kinase in two-component regulatory system with PhoB; Member of the two-component regulatory system PhoR/PhoB involved in the phosphate regulon genes expression. PhoR may function as a membrane-associated protein kinase that phosphorylates PhoB in response to environmental signals.
  
  
 0.922
phnD
Phosphonates-binding periplasmic protein; Phosphonate binding protein that is part of the phosphonate uptake system. Exhibits high affinity for 2-aminoethylphosphonate, and somewhat less affinity to ethylphosphonate, methylphosphonate, phosphonoacetate and phenylphosphonate.
   
 
 0.854
phoB
Response regulator in two-component regulatory system with PhoR; This protein is a positive regulator for the phosphate regulon. Transcription of this operon is positively regulated by PhoB and PhoR when phosphate is limited.
 
  
 0.852
pitB
Phosphate transporter; Low-affinity inorganic phosphate transport; Belongs to the inorganic phosphate transporter (PiT) (TC 2.A.20) family. Pit subfamily.
     
 0.841
phnC
Phosphonate ABC transporter ATPase; Part of the ABC transporter complex PhnCDE involved in phosphonates, phosphate esters, phosphite and phosphate import. Responsible for energy coupling to the transport system.
   
  
 0.752
ugpE
Sn-glycerol-3-phosphate ABC transporter permease; Part of the binding-protein-dependent transport system for sn-glycerol-3-phosphate; probably responsible for the translocation of the substrate across the membrane.
