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

Score
proPMFS family low-affinity proline 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 (By similarity); Belongs to the major facilitator superfamily. Metabolite:H+ Symporter (MHS) family (TC 2.A.1.6) family. (500 aa)    
Predicted Functional Partners:
putP
SSS family major sodium/proline symporter; Catalyzes the sodium-dependent uptake of extracellular L- proline; Belongs to the sodium:solute symporter (SSF) (TC 2.A.21) family.
   
  
 0.864
osmV
ABC-type proline/glycine betaine transport system; Part of the OsmU ABC transporter complex, which is involved in the uptake of osmoprotectants such as choline-O-sulfate and glycine betaine. Probably responsible for energy coupling to the transport system.
      
 0.763
proQ
Activator of proP; RNA chaperone with significant RNA binding, RNA strand exchange and RNA duplexing activities. May regulate ProP activity through an RNA-based, post-transcriptional mechanism. Belongs to the ProQ family.
      
 0.760
otsB
Trehalose-6-phosphate phophatase, biosynthetic; Removes the phosphate from trehalose 6-phosphate to produce free trehalose.
   
  
 0.705
otsA
Trehalose-6-phosphate synthase; Probably involved in the osmoprotection via the biosynthesis of trehalose. 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; Belongs to the glycosyltransferase 20 family.
   
  
 0.691
rpmE2
Putative 50S ribosomal protein L31 (second copy); Similar to E. coli putative ribosomal protein (AAC73399.1); Blastp hit to AAC73399.1 (87 aa), 74% identity in aa 1 - 86.
   
    0.523
osmY-2
ABC-type transport system protein; Part of the OsmU ABC transporter complex, which is involved in the uptake of osmoprotectants such as choline-O-sulfate and glycine betaine. Probably responsible for the translocation of the substrate across the membrane.
      
 0.523
STM2342
Putative inner membrane protein; Similar to E. coli orf, hypothetical protein (AAC77150.1); Blastp hit to AAC77150.1 (484 aa), 27% identity in aa 30 - 483.
   
    0.518
rpoS
Sigma S (sigma 38) factor of RNA polymerase; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the master transcriptional regulator of the stationary phase and the general stress response.
      
 0.507
rpmJ2
Putative 50S ribosomal protein L36 (second copy); Belongs to the bacterial ribosomal protein bL36 family.
   
    0.495
