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

pepTTripeptidase; Cleaves the N-terminal amino acid of tripeptides. Belongs to the peptidase M20B family. (407 aa)    
Predicted Functional Partners:
pepQ
Dipeptidase; Belongs to the peptidase M24B family.
  
 
 0.906
pepP
Aminopeptidase P; XAA-pro aminopeptidase; Belongs to the peptidase M24B family.
  
 
 0.885
pepN
Lysyl-aminopeptidase, aminopeptidase N.
      
 0.827
pepO
Endopeptidase O.
   
  
 0.826
pepV
Dipeptidase.
     
 0.819
pepXP
X-prolyl dipeptidyl peptidase; Removes N-terminal dipeptides sequentially from polypeptides having unsubstituted N-termini provided that the penultimate residue is proline; Belongs to the peptidase S15 family.
      
 0.817
pepM
Methionine aminopeptidase; 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.
  
  
 0.812
pepS
Aminopeptidase PepS.
  
  
 0.807
dtpT
Di- or tripeptide:H+ symporter; Belongs to the PTR2/POT transporter (TC 2.A.17) family.
   
  
 0.776
stu1138
Pore-forming peptide, putative.
