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

dtpDDipeptide and tripeptide permease D; Probable proton-dependent permease that transports dipeptides; Belongs to the PTR2/POT transporter (TC 2.A.17) family. DtpD subfamily. (493 aa)    
Predicted Functional Partners:
yhhH
Putative NTF2 fold immunity protein for polymorphic toxin RhsB.
      
 0.601
yjcE
Putative cation/proton antiporter.
   
 
 0.560
dtpB
Dipeptide and tripeptide permease B; Proton-dependent permease that transports di- and tripeptides. Has a clear preference for dipeptides and tripeptides composed of L-amino acids, and discriminates dipeptides on the basis of the position of charges within the substrate. Belongs to the PTR2/POT transporter (TC 2.A.17) family. DtpB subfamily.
  
   
0.494
yjeM
Putative transport.
  
 
 
 0.478
emrD
Multidrug efflux system protein; Multidrug resistance pump that participates in a low energy shock adaptive response; Belongs to the major facilitator superfamily.
      
 0.476
dtpA
Dipeptide and tripeptide permease A; Proton-dependent permease that transports di- and tripeptides as well as structurally related peptidomimetics such as aminocephalosporins into the cell. Has a clear preference for dipeptides and tripeptides composed of L-amino acids, and discriminates dipeptides on the basis of the position of charges within the substrate; Belongs to the PTR2/POT transporter (TC 2.A.17) family. DtpA subfamily.
  
  
0.470
ybgI
NIF3 family metal-binding protein; Provides significant protection from radiation damage and may be involved in the degradation of radiation-damaged nucleotides.
       0.434
ygjI
Putative oxidoreductase.
  
 
 
 0.406
yajR
Putative transport protein; Protein involved in response to drug.
   
  
 0.404
ygiS
Putative ABC transporter permease; Probably part of a deoxycholate transport system. Its expression in the presence of deoxycholate in a ygiS deletion mutant increases intracellular deoxycholate levels and decreases cell growth; higher expression in the presence of deoxycholate inhibits cell growth completely. Bile acid detergents such as deoxycholate are important for host defense against bacterial growth in the gall bladder and duodenum. Belongs to the bacterial solute-binding protein 5 family.
