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

pepE(alpha)-aspartyl dipeptidase; Hydrolyzes dipeptides containing N-terminal aspartate residues. May play a role in allowing the cell to use peptide aspartate to spare carbon otherwise required for the synthesis of the aspartate family of amino acids. (229 aa)    
Predicted Functional Partners:
iadA
Isoaspartyl dipeptidase; Catalyzes the hydrolytic cleavage of a subset of L- isoaspartyl (L-beta-aspartyl) dipeptides. Used to degrade proteins damaged by L-isoaspartyl residues formation.
  
  
 0.903
ybeK
Putative purine nucleoside hydrolase; Hydrolyzes cytidine or uridine to ribose and cytosine or uracil, respectively.
  
   
 0.788
yjjU
Putative phosphoesterase; Similar to E. coli orf, hypothetical protein (AAC77330.1); Blastp hit to AAC77330.1 (357 aa), 85% identity in aa 1 - 357.
      
 0.716
priA
Primosomal protein N; Involved in the restart of stalled replication forks. Recognizes and binds the arrested nascent DNA chain at stalled replication forks. It can open the DNA duplex, via its helicase activity, and promote assembly of the primosome and loading of the major replicative helicase DnaB onto DNA; Belongs to the helicase family. PriA subfamily.
      
 0.658
purN
Polyphosphate kinase; Catalyzes the transfer of a formyl group from 10- formyltetrahydrofolate to 5-phospho-ribosyl-glycinamide (GAR), producing 5-phospho-ribosyl-N-formylglycinamide (FGAR) and tetrahydrofolate.
 
      0.604
ybiK
Putative asparaginase; Degrades proteins damaged by L-isoaspartyl residue formation (also known as beta-Asp residues). Degrades L-isoaspartyl-containing di- and tripeptides. Acts best on iso-Asp-Leu, followed by iso-Asp-Ala, -His and to a lesser extent iso-Asp-Lys, -Phe and iso-Asp-Leu-Ala. Does not act on internal iso-Asp bonds (Als-iso-Asp-Leu-Ala). Does not act on alpha-Asp bonds. Has poor L-asparaginase activity. Belongs to the Ntn-hydrolase family.
  
  
 0.583
pepT
Putative peptidase T; Cleaves the N-terminal amino acid of tripeptides. Hydrolyzes tripeptides containing N-terminal methionine, leucine, or phenylalanine. Displays little or no activity against dipeptides, N- blocked or C-blocked tripeptides, and tetrapeptides. Belongs to the peptidase M20B family.
 
 
 0.578
ytjA
Putative inner membrane protein.
      
 0.572
STM4191
Putative cytoplasmic protein.
       0.558
sspA
Stringent starvation protein A; Regulator of transcription; similar to E. coli regulator of transcription; stringent starvation protein A (AAC76261.1); Blastp hit to AAC76261.1 (212 aa), 98% identity in aa 1 - 211; Belongs to the GST superfamily.
