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

pstBPhosphate import ATP-binding protein PstB; 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. (267 aa)    
Predicted Functional Partners:
pstA
Phosphate ABC transporter (permease); Function of homologous gene experimentally demonstrated in an other organism; transporter.
 
 
 0.997
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.
 
 
 0.997
pstS
Phosphate ABC transporter (binding lipoprotein); Function of homologous gene experimentally demonstrated in an other organism; transporter.
 
 
 0.987
pstS-2
Phosphate-binding protein PstS 1; Function of homologous gene experimentally demonstrated in an other organism; transporter.
 
 
 0.986
phoU
Negative regulator of PhoR/PhoB two-component regulator; Plays a role in the regulation of phosphate uptake.
 
  
 0.973
guaA
GMP synthetase (glutamine aminotransferase); Catalyzes the synthesis of GMP from XMP.
 
   
 0.664
gltB-2
Glutamate synthase, large subunit; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
     
 0.607
yfiC
ABC-type transport system, multidrug-family ATP-binding/permease protein; Function of strongly homologous gene; transporter.
 
     
0.581
ftsZ
Cell division protein FtsZ; Essential cell division protein that forms a contractile ring structure (Z ring) at the future cell division site. The regulation of the ring assembly controls the timing and the location of cell division. One of the functions of the FtsZ ring is to recruit other cell division proteins to the septum to produce a new cell wall between the dividing cells. Binds GTP and shows GTPase activity.
   
 
 0.477
SCA91846.1
Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative transporter.
     
0.463
