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:
some 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

Predicted Functional Partners:
pstB
Phosphate transport system atp-binding protein; Part of the ABC transporter complex PstSACB involved in phosphate import. Responsible for energy coupling to the transport system
 
 
 0.998
pstS
Phosphate transport system substrate-binding protein; Binds 1 inorganic phosphate per subunit with a KD of 0.34 uM . Required for phosphate transport . In strain PAO1 implicated in host cell adhesion; in some virulent strains (e.g. MDR25 which expresses very high levels of this protein) antibody fragments against this protein decrease host cell adhesion and increase transepithelial resistance of human epithelial cell monolayers. Its ability to bind phosphate may allow it to acquire phosphate from its host
 
 
 0.998
pstA
3a0107s02c: phosphate ABC transporter, permease protein PstA
 
0.993
phoU
Phosphate transport system regulatory protein phou; Plays a role in the regulation of phosphate uptake
 
  
 0.977
DR97_5623
annotation not available
 
 
 0.903
phoB
Two-component system, ompr family, phosphate regulon response regulator phob; 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
  
  
 0.891
phoR
Two-component system, ompr family, phosphate regulon sensor histidine kinase phor; 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
 
  
 0.882
DR97_1429
annotation not available
     
 0.862
phoA2
Alkaline phosphatase l; Has both a phosphomonoesterase and phosphodiesterase activity
     
 0.862
ppk1
Polyphosphate kinase 1; Catalyzes the reversible transfer of the terminal phosphate of ATP to form a long-chain polyphosphate (polyP)
     
 0.736
