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

Score
pepACytosol aminopeptidase; Presumably involved in the processing and regular turnover of intracellular proteins. Catalyzes the removal of unsubstituted N- terminal amino acids from various peptides. (497 aa)    
Predicted Functional Partners:
gshB2
Glutathione synthetase; Belongs to the prokaryotic GSH synthase family.
   
 
 0.926
PepN
Aminopeptidase N.
  
 0.925
ACP27199.1
Leucyl aminopeptidase; Belongs to the peptidase M17 family.
  
  
 
0.920
pepD
Aminoacyl-histidine dipeptidase.
   
 
 0.919
ACP24181.1
Glutamate-cysteine ligase protein; Catalyzes the synthesis of gamma-glutamylcysteine (gamma-GC). Belongs to the glutamate--cysteine ligase type 2 family. EgtA subfamily.
     
  0.900
ACP26454.1
Putative cation transport protein ChaC-related; Catalyzes the cleavage of glutathione into 5-oxo-L-proline and a Cys-Gly dipeptide. Acts specifically on glutathione, but not on other gamma-glutamyl peptides; Belongs to the gamma-glutamylcyclotransferase family.
     
  0.900
ACP27408.1
Cation transport protein, ChaC related; Catalyzes the cleavage of glutathione into 5-oxo-L-proline and a Cys-Gly dipeptide. Acts specifically on glutathione, but not on other gamma-glutamyl peptides; Belongs to the gamma-glutamylcyclotransferase family.
     
  0.900
glyA
Serine hydroxymethyltransferase 1; 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.
  
 
 0.828
cysK2
Cysteine synthase protein.
   
 0.823
cysK1
Cysteine synthase A.
   
 0.823
