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

oppA2Oligopeptide-binding protein oppA2 precursor; Bacterial extracellular solute-binding protein; High confidence in function and specificity. (600 aa)    
Predicted Functional Partners:
oppB2
Binding-protein-dependent transport systems inner membrane component; High confidence in function and specificity.
 
 
 0.935
oppC2
Binding-protein-dependent transport systems inner membrane component; High confidence in function and specificity.
 
 
 0.929
oppB
Binding-protein-dependent transport systems inner membrane component; High confidence in function and specificity.
 
 
 0.917
oppC
Binding-protein-dependent transport systems inner membrane component; High confidence in function and specificity.
 
 
 0.908
oppD
Oligopeptide transport ATP-binding protein oppD; High confidence in function and specificity; Belongs to the ABC transporter superfamily.
 
  
 0.786
oppF
Oligopeptide transport ATP-binding protein oppF; High confidence in function and specificity; Belongs to the ABC transporter superfamily.
 
  
 0.786
nifJ
NifJ protein; Pyruvate:ferredoxin (flavodoxin) oxidoreductase, Thiamine pyrophosphate enzyme, C-terminal TPP binding domain, pyruv_ox_red: pyruvate:ferredoxin (flavodoxin) oxidoreductase; High confidence in function and specificity.
  
  
 0.782
dtpT
Di-/tripeptide transporter; Proton-dependent uptake of di- or tri-peptides; Belongs to the PTR2/POT transporter (TC 2.A.17) family.
      
 0.469
pepM
PepM protein; Removes the N-terminal methionine from nascent proteins. The N-terminal methionine is often cleaved when the second residue in the primary sequence is small and uncharged (Met-Ala-, Cys, Gly, Pro, Ser, Thr, or Val). Requires deformylation of the N(alpha)-formylated initiator methionine before it can be hydrolyzed; Belongs to the peptidase M24A family. Methionine aminopeptidase type 1 subfamily.
      
 0.461
dppB
Pseudogene; Dipeptide-binding protein precursor., Contains stopcodon at position 706; High confidence in function and specificity.
  
 
 0.459
