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

EH31_09855Cytosol aminopeptidase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the peptidase M17 family. (461 aa)    
Predicted Functional Partners:
pepN
Derived by automated computational analysis using gene prediction method: Protein Homology.
  
 0.938
pepA
Aminopeptidase A; Presumably involved in the processing and regular turnover of intracellular proteins. Catalyzes the removal of unsubstituted N- terminal amino acids from various peptides.
  
  
 
0.933
gshB
Glutathione synthetase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the prokaryotic GSH synthase family.
   
 
 0.930
EH31_12290
Gamma-glutamyltranspeptidase; Derived by automated computational analysis using gene prediction method: Protein Homology.
     
 0.919
EH31_01665
Cysteine synthase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the cysteine synthase/cystathionine beta- synthase family.
    
 0.875
EH31_09905
Cysteine synthase; CysK; forms a complex with serine acetyltransferase CysE; functions in cysteine biosynthesis; Derived by automated computational analysis using gene prediction method: Protein Homology.
    
 0.875
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.
  
 
 0.872
EH31_09845
N-acetyl-gamma-glutamyl-phosphate reductase; Catalyzes the reduction of N-acetyl-5-glutamyl phosphate to N-acetyl-L-glutamate 5-semialdehyde in arginine biosynthesis; Derived by automated computational analysis using gene prediction method: Protein Homology.
       0.637
EH31_09850
Hypothetical protein; Derived by automated computational analysis using gene prediction method: Protein Homology.
       0.637
map
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.
