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

pepNProbable aminopeptidase N; Alternative locus ID: PMED4_11281. (869 aa)    
Predicted Functional Partners:
pepA
Cytosol aminopeptidase; Presumably involved in the processing and regular turnover of intracellular proteins. Catalyzes the removal of unsubstituted N- terminal amino acids from various peptides.
  
 0.943
gshB
Putative Glutathione synthetase; Citation: Gushima et al. (1984) Nucleic Acids Res. 12:9299-9307; Alternative locus ID: PMED4_01841.
  
  
 0.924
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.
    
 0.841
cysK2
O-acetylserine (thiol)-lyase A; Alternative locus ID: PMED4_01291; Belongs to the cysteine synthase/cystathionine beta- synthase family.
 
 
 
 0.823
cysK1
O-acetylserine (thiol)-lyase A; Alternative locus ID: PMED4_04501; Belongs to the cysteine synthase/cystathionine beta- synthase family.
 
   
 0.823
aspC
Aminotransferases class-I; Possible role in phosphonate metabolism; Alternative locus ID: PMED4_07301.
   
 
 0.809
PMM1932
Conserved hypothetical protein; Alternative locus ID: PMED4_11271.
       0.674
htpG
Heat shock protein HtpG; Molecular chaperone. Has ATPase activity.
    
 
 0.661
fusA
Elongation factor G; Catalyzes the GTP-dependent ribosomal translocation step during translation elongation. During this step, the ribosome changes from the pre-translocational (PRE) to the post-translocational (POST) state as the newly formed A-site-bound peptidyl-tRNA and P-site-bound deacylated tRNA move to the P and E sites, respectively. Catalyzes the coordinated movement of the two tRNA molecules, the mRNA and conformational changes in the ribosome; Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. EF-G/EF-2 subfamily.
   
 
 0.528
thrC
Threonine synthase: Pyridoxal-5'-phosphate-dependent enzymes, beta family; Catalyzes the gamma-elimination of phosphate from L- phosphohomoserine and the beta-addition of water to produce L- threonine.
   
  
 0.500
