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

pepDProbable 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. (486 aa)    
Predicted Functional Partners:
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.
   
 
 0.932
pepN
PepN 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.
     
 0.928
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.
   
 
 0.913
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.
     
 0.906
gshA
GshA protein; Glutamate--cysteine ligase. Glutathione metabolism; High confidence in function and specificity.
     
 0.893
azo3380
Conserved hypothetical transaminase; Region start changed from 3714581 to 3714479 (102 bases).
    
 0.888
cysK
Cysteine synthase A,; High confidence in function and specificity; Belongs to the cysteine synthase/cystathionine beta- synthase family.
    
 0.874
pepP
Xaa-Pro aminopeptidase,; Specificity unclear.
  
 
 0.815
fliD
Flagellar hook-associated protein; Required for morphogenesis and for the elongation of the flagellar filament by facilitating polymerization of the flagellin monomers at the tip of growing filament. Forms a capping structure, which prevents flagellin subunits (transported through the central channel of the flagellum) from leaking out without polymerization at the distal end.
   
   0.732
guaB
IMP dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
