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

pepNLysyl-aminopeptidase, aminopeptidase N. (846 aa)    
Predicted Functional Partners:
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.
 
   
 0.923
gshAB
Conserved hypothetical protein; Synthesizes glutathione from L-glutamate and L-cysteine via gamma-L-glutamyl-L-cysteine.
     
 0.909
metB2
Cystathionine beta-lyase.
  
 
 0.900
pepO
Endopeptidase O.
 
   
 0.886
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.
   
 
 0.851
pepP
Aminopeptidase P; XAA-pro aminopeptidase; Belongs to the peptidase M24B family.
  
 
 0.849
glyA
Serine hydroxymethyltransferase; Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism.
    
 0.848
pepT
Tripeptidase; Cleaves the N-terminal amino acid of tripeptides. Belongs to the peptidase M20B family.
      
 0.827
pepQ
Dipeptidase; Belongs to the peptidase M24B family.
  
 
 0.826
cysM1
Cysteine synthase; Belongs to the cysteine synthase/cystathionine beta- synthase family.
    
 0.813
