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

pepQDipeptidase; Belongs to the peptidase M24B family. (361 aa)    
Predicted Functional Partners:
pepT
Tripeptidase; Cleaves the N-terminal amino acid of tripeptides. Belongs to the peptidase M20B family.
  
 
 0.906
pepV
Dipeptidase.
   
 
 0.834
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.
  
   
 0.834
pepN
Lysyl-aminopeptidase, aminopeptidase N.
  
 
 0.826
pepO
Endopeptidase O.
   
  
 0.811
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.
  
  
 0.807
pepS
Aminopeptidase PepS.
  
  
 0.760
guaB
Inosine monophosphate dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
   
 
 0.659
ccpA
Catabolite control protein.
  
 
 0.611
prtM
Protease maturation protein precursor; Plays a major role in protein secretion by helping the post- translocational extracellular folding of several secreted proteins.
 
   
 0.507
