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

pstSBinds 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 (323 aa)    
Predicted Functional Partners:
pstA
3a0107s02c: phosphate ABC transporter, permease protein PstA
 
 
 0.999
pstC
annotation not available
 
 
 0.998
pstB
Part of the ABC transporter complex PstSACB involved in phosphate import. Responsible for energy coupling to the transport system
 
 
 0.997
phoU
Plays a role in the regulation of phosphate uptake.
 
 
 0.983
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
  
  
 0.958
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
 
  
 0.939
ctpL
Chemotactic-signal transducers respond to changes in the concentration of attractants and repellents in the environment, transduce a signal from the outside to the inside of the cell, and facilitate sensory adaptation through the variation of the level of methylation. Chemoreceptor for inorganic phosphate, which is required for taxis at low concentrations of phosphate. Is also responsible for the positive chemotaxis toward 4-chloroaniline (4CA) and catechol . Does not recognize inorganic phosphate directly, but via a complex between the periplasmic protein PstS and inorganic phosphate .

ppk1
Catalyzes the reversible transfer of the terminal phosphate of ATP to form a long-chain polyphosphate (polyP)
