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

dcpDipeptidyl carboxypeptidase II; Removes dipeptides from the C-termini of N-blocked tripeptides, tetrapeptides and larger peptides. Belongs to the peptidase M3 family. (681 aa)    
Predicted Functional Partners:
ydfG
NADP-dependent 3-hydroxy acid dehydrogenase; NADP-dependent dehydrogenase with broad substrate specificity acting on 3-hydroxy acids. Catalyzes the NADP-dependent oxidation of L- allo-threonine to L-2-amino-3-keto-butyrate, which is spontaneously decarboxylated into aminoacetone. Also acts on D-threonine, L-serine, D-serine, D-3-hydroxyisobutyrate, L-3-hydroxyisobutyrate, D-glycerate and L-glycerate. Able to catalyze the reduction of the malonic semialdehyde to 3-hydroxypropionic acid. YdfG is apparently supplementing RutE, the presumed malonic semialdehyde reductase involved in pyrimi [...]

malI
Transcriptional repressor of Mal regulon; Repressor for the malX and malY genes. Also regulates its own expression. Binds maltose as an inducer.
      
 0.529
loiP
Phe-Phe periplasmic metalloprotease, OM lipoprotein; Metalloprotease that cleaves substrates preferentially between Phe-Phe residues. Plays a role in response to some stress conditions. Seems to regulate the expression of speB.
  
  
 0.460
ptrB
Protease II; Cleaves peptide bonds on the C-terminal side of lysyl and argininyl residues; Belongs to the peptidase S9A family.
  
   
 0.451
hdhA
7-alpha-hydroxysteroid dehydrogenase, NAD-dependent; Catalyzes the oxidation of the 7-alpha-hydroxy group of primary bile acids such as cholate, chenodeoxycholate and taurochenodeoxycholate. To a lesser extent, also able to use taurocholate and glycocholate.
