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

pepQProline dipeptidase; Splits dipeptides with a prolyl residue in the C-terminal position. (443 aa)    
Predicted Functional Partners:
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.
  
 
 0.931
pepN
Similar to E. coli aminopeptidase N (AAC74018.1); Blastp hit to AAC74018.1 (870 aa), 94% identity in aa 1 - 870.
  
 
 0.876
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.
  
 
 0.863
yigZ
Putative cytoplasmic protein; Similar to E. coli orf, hypothetical protein (AAC76851.1); Blastp hit to AAC76851.1 (205 aa), 91% identity in aa 2 - 205.
 
  
 0.852
pepD
Similar to E. coli aminoacyl-histidine dipeptidase (peptidase D) (AAC73341.1); Blastp hit to AAC73341.1 (485 aa), 92% identity in aa 1 - 485.
  
 
 0.818
trkH
Trk family potassium transport protein; Low-affinity potassium transport system. Interacts with Trk system potassium uptake protein TrkA and requires TrkE for transport activity (By similarity); Belongs to the TrkH potassium transport family.
  
  
 0.728
hemG
Protoporphyrin oxidase; Catalyzes the 6-electron oxidation of protoporphyrinogen-IX to form protoporphyrin-IX using menaquinone as electron acceptor.
  
    0.697
fadB
3-hydroxyacyl-coA dehydrogenase of 4-enzyme FadB protein; Involved in the aerobic and anaerobic degradation of long- chain fatty acids via beta-oxidation cycle. Catalyzes the formation of 3-oxoacyl-CoA from enoyl-CoA via L-3-hydroxyacyl-CoA. It can also use D-3-hydroxyacyl-CoA and cis-3-enoyl-CoA as substrate. In the C-terminal section; belongs to the 3-hydroxyacyl-CoA dehydrogenase family.
  
 
 0.597
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.
 
  
 0.582
fadA
3-ketoacyl-CoA thiolase; Catalyzes the final step of fatty acid oxidation in which acetyl-CoA is released and the CoA ester of a fatty acid two carbons shorter is formed. Involved in the aerobic and anaerobic degradation of long-chain fatty acids (By similarity).
