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

pepFEvidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme. (670 aa)    
Predicted Functional Partners:
pepT
Peptidase T (tripeptidase); Cleaves the N-terminal amino acid of tripeptides. Belongs to the peptidase M20B family.
  
  
 0.916
coiA
Protein involved in establishment of DNA transport in competence; Required for optimal transformation.
  
  
 0.723
dtpT
Di-tripeptide-proton ABC symporter; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type t: transporter.
  
  
 0.668
pepA
Leucyl aminopeptidase; Presumably involved in the processing and regular turnover of intracellular proteins. Catalyzes the removal of unsubstituted N- terminal amino acids from various peptides (By similarity).
  
  
 0.636
ccpA
Transcriptional regulator (Lacl family); Global transcriptional regulator of carbon catabolite repression (CCR) and carbon catabolite activation (CCA), which ensures optimal energy usage under diverse conditions. Interacts with either P- Ser-HPr or P-Ser-Crh, leading to the formation of a complex that binds to DNA at the catabolite-response elements (cre). Binding to DNA allows activation or repression of many different genes and operons.
    
   0.570
ldcA
Muropeptide L,D-carboxypeptidase; May be involved in the degradation of peptidoglycan by catalyzing the cleavage of the terminal D-alanine residue from cytoplasmic murein peptides; Belongs to the peptidase S66 family.
      
 0.543
ymfH
Putative processing protease; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
   
 
 0.540
yugJ
Putative NADH-dependent butanol dehydrogenase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
   
    0.511
hmoB
Heme-degrading monooxygenase; Catalyzes the oxidative degradation of the heme macrocyclic porphyrin ring in the presence of a suitable electron donor such as ascorbate or NADPH--cytochrome P450 reductase, with subsequent release of free iron; Belongs to the antibiotic biosynthesis monooxygenase family.
   
    0.502
purB
Adenylosuccinate lyase; Influences the affinity of glutamyl--tRNA ligase for its substrates and increases its thermostability; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.
  
    0.496
