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

pepNPepN protein; Aminopeptidase catalyzes the removal of single amino acids from the amino terminus of small peptides and probable plays a role in their final digestion. Similar to trembl|Q8XXI8 (50%) and to sprot|AMPN_ECOLI (47%). Pfam (PF01433): Aminopeptidase N, APN (CD13); Specificity unclear. (894 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.
  
 0.957
pepD
Probable aminoacyl-histidine dipeptidase (EC 3.4.13.3) (Xaa-His dipeptidase) (X-His dipeptidase) (Beta-alanyl-histidine dipeptidase) (Carnosinase) (Peptidase D). Homology to pepD of E. coli of 44%. THIS DIPEPTIDASE HAS SPECIFICITY FOR THE UNUSUAL DIPEPTIDE BETA-ALANYL-L-HISTIDINE. InterPro: Peptidase family M20/M25/M40 (IPR002933) Pfam: Peptidase family M20/M25/M40 no signal peptide no TMHs; High confidence in function and specificity.
     
 0.928
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.
    
 0.926
cysK
Cysteine synthase A,; High confidence in function and specificity; Belongs to the cysteine synthase/cystathionine beta- synthase family.
   
 0.910
gshB
Glutathione synthetase (GSH synthetase) (GSH-S) (GSHase). InterPro: Prokaryotic glutathione synthetase ATP-binding domain; High confidence in function and specificity; Belongs to the prokaryotic GSH synthase family.
    
 0.902
ggt
Ggt protein; Gamma-glutamyltranspeptidase catalyzes the transfer of the gamma-glutamyl moiety of glutathione to an acceptor that may be an amino acid, a peptide or water (forming glutamate). GGT plays a key role in the gamma-glutamyl cycle, a pathway for the synthesis and degradation of glutathione and drug and xenobiotic detoxification. Similar to trembl|Q88H30 (43%)and to trembl|Q8UJH0 (36%). TIGRfam (TIGR00066): Gamma-glutamyltranspeptidase Pfam (PF01019): Gamma-glutamyltranspeptidase SignalP reporting Signal peptide; Specificity unclear.
     
 0.901
gshA
GshA protein; Glutamate--cysteine ligase. Glutathione metabolism; High confidence in function and specificity.
   
 
 0.900
tyrB
Probable aromatic-amino-acid aminotransferase. Homology to tyrB of E. coli of 52% (sprot|TYRB_ECO). Is involved in biosynthesis of phe, tyr, asp and leu. Catalyse the reactiion: an aromatic amino acid + 2-oxoglutarate = an aromatic oxo acid + l-glutamate. Pfam: Aminotransferase class I and II no signal peptide no TMHs; High confidence in function and specificity.

icd1
Isocitrate dehydrogenase [NADP]. Homology to icd1 of A. eutropus of 75% (trembl|Q8KLU5) Isocitrate dehydrogenase is an important enzyme of the TCA which catalyzes the reaction: isocitrate + NAD+ = 2-oxoglutarate + CO2 + NADH + H+ Pfam: Isocitrate/isopropylmalate dehydrogenase Tigrfam: prok_nadp_idh: isocitrate dehydrogenase no signal peptide no TMHs; High confidence in function and specificity.

fusA1
Putative elongation factor EF-G. Homology to FusA of E. coli of 29% (sprot|EFG_ECOLI(SRS)) This protein promotes the GTP-dependent translocation of the nascent protein chain from the A-site to the P-site of the ribosome. Interpro: Elongation factor G, C-terminus (IPR000640); Elongation factor Tu domain 2 (IPR004161); GTP-binding elongation factor (IPR000795); ATP/GTP-binding site motifA (P-loop) (IPR001687) Tigrfam: EF-G: translation elongation factor G Pfam: Elongation factor Tu domain 2; Elongation factor Tu GTP binding domain; Elongation factor G C-terminus no signal peptide no TMHs [...]
