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

proPProline/glycine betaine transporter; Proton symporter that senses osmotic shifts and responds by importing osmolytes such as proline, glycine betaine, stachydrine, pipecolic acid, ectoine and taurine. It is both an osmosensor and an osmoregulator which is available to participate early in the bacterial osmoregulatory response; Belongs to the major facilitator superfamily. Metabolite:H+ Symporter (MHS) family (TC 2.A.1.6) family. (500 aa)    
Predicted Functional Partners:
putP
Proline:sodium symporter; Catalyzes the sodium-dependent uptake of extracellular L- proline. This protein is also capable of using lithium as the transport cation. Also catalyzes the uptake of propionate.
   
  
 0.815
betT
Choline transporter of high affinity; High-affinity uptake of choline driven by a proton-motive force; Belongs to the BCCT transporter (TC 2.A.15) family.
      
 0.811
proQ
RNA chaperone, putative ProP translation regulator; RNA chaperone with significant RNA binding, RNA strand exchange and RNA duplexing activities. May regulate ProP activity through an RNA-based, post-transcriptional mechanism.
      
 0.811
proX
Glycine betaine/proline ABC transporter periplasmic binding protein; Part of the ProU ABC transporter complex involved in glycine betaine and proline betaine uptake. Binds glycine betaine and proline betaine with high affinity.
      
 0.790
mscS
Mechanosensitive channel protein, small conductance; Mechanosensitive channel that participates in the regulation of osmotic pressure changes within the cell, opening in response to stretch forces in the membrane lipid bilayer, without the need for other proteins. Contributes to normal resistance to hypoosmotic shock. Forms an ion channel of 1.0 nanosiemens conductance with a slight preference for anions. The channel is sensitive to voltage; as the membrane is depolarized, less tension is required to open the channel and vice versa. The channel is characterized by short bursts of activ [...]
   
  
 0.760
proW
Glycine betaine/proline ABC transporter permease; Part of the ProU ABC transporter complex involved in glycine betaine and proline betaine uptake. Probably responsible for the translocation of the substrate across the membrane (Probable); Belongs to the binding-protein-dependent transport system permease family. CysTW subfamily.
      
 0.645
clsA
Cardiolipin synthase 1; Catalyzes the reversible phosphatidyl group transfer from one phosphatidylglycerol molecule to another to form cardiolipin (CL) (diphosphatidylglycerol) and glycerol.
   
  
 0.644
otsA
Trehalose-6-phosphate synthase; Catalyzes the transfer of glucose from UDP-alpha-D-glucose (UDP-Glc) to D-glucose 6-phosphate (Glc-6-P) to form trehalose-6- phosphate. Acts with retention of the anomeric configuration of the UDP-sugar donor. Essential for viability of the cells at low temperatures and at elevated osmotic strength. Belongs to the glycosyltransferase 20 family.
   
  
 0.637
proV
Glycine betaine/proline ABC transporter periplasmic binding protein; Part of the ProU ABC transporter complex involved in glycine betaine and proline betaine uptake. Probably responsible for energy coupling to the transport system (Probable).
      
 0.598
caiT
Putative transporter; Catalyzes the exchange of L-carnitine for gamma-butyrobetaine and related betaines.
      
 0.569
