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

pepALeucine aminopeptidase; Presumably involved in the processing and regular turnover of intracellular proteins. Catalyzes the removal of unsubstituted N- terminal amino acids from various peptides. (487 aa)    
Predicted Functional Partners:
pepN
Probable aminopeptidase N.
  
 0.943
SYNW1394
Putative gamma-glutamyltranspeptidase.
     
 0.920
gshB
Putative glutathione synthetase; Citation: Gushima et al. (1984) Nucleic Acids Res. 12:9299-9307.
   
 
 0.915
glyA
Serine hydroxymethyltransferase (SHMT); 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.
  
 
 0.823
cysK1
O-acetylserine (thiol)-lyase A; Belongs to the cysteine synthase/cystathionine beta- synthase family.
    
 0.822
cysK2
O-acetylserine (thiol)-lyase A; Belongs to the cysteine synthase/cystathionine beta- synthase family.
    
 0.822
aspC
Aminotransferases class-I; Possible role in phosphonate metabolism.
   
  0.812
metB
Putative cystathionine gamma-synthase.
   
 
  0.800
SYNW0561
Hypothetical.
       0.775
metH
Putative methionine synthase; Catalyzes the transfer of a methyl group from methyl- cobalamin to homocysteine, yielding enzyme-bound cob(I)alamin and methionine. Subsequently, remethylates the cofactor using methyltetrahydrofolate.
