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

dppDDipeptide ABC transporter (ATP-binding protein); Part of the binding-protein-dependent transport system for dipeptides. Probably responsible for energy coupling to the transport system. Expressed to facilitate adaptation to nutrient deficiency conditions, which also induce sporulation; Belongs to the ABC transporter superfamily. (335 aa)    
Predicted Functional Partners:
dppB
Dipeptide ABC transporter (permease); Part of the binding-protein-dependent transport system for dipeptides; probably responsible for the translocation of the substrate across the membrane. Is expressed to facilitate adaptation to nutrient deficiency conditions.
 0.999
dppC
Dipeptide ABC transporter (permease); Part of the binding-protein-dependent transport system for dipeptides; probably responsible for the translocation of the substrate across the membrane. Is expressed to facilitate adaptation to nutrient deficiency conditions, which also induce sporulation.
 
 0.999
dppE
Dipeptide ABC transporter (dipeptide-binding lipoprotein); Part of the binding-protein-dependent transport system for dipeptides; probably responsible for the binding of dipeptides with high affinity. Is expressed to facilitate adaptation to nutrient deficiency conditions, which also induce sporulation; Belongs to the bacterial solute-binding protein 5 family.
 
 0.998
appC
Oligopeptide ABC transporter (permease); This protein is a component of an oligopeptide permease, a binding protein-dependent transport system. This APP system can completely substitute for the OPP system in both sporulation and genetic competence, though, unlike OPP, is incapable of transporting tripeptides. Probably responsible for the translocation of the substrate across the membrane (By similarity); Belongs to the binding-protein-dependent transport system permease family. OppBC subfamily.
  
 0.993
oppC
Oligopeptide ABC transporter (permease); Part of the binding-protein-dependent transport system for oligopeptides; probably responsible for the translocation of the substrate across the membrane. Also required for sporulation and competence.
  
 0.990
dppA
D-alanyl-aminopeptidase; Hydrolyzes N-terminal residues in D-amino acid containing peptides. Among the tested substrates, the highest activities are with D-Ala-D-Ala and D-Ala-Gly-Gly. The physiological role is not clear; Belongs to the peptidase M55 family.
  
  
 0.972
appB
Oligopeptide ABC transporter (oligopeptide-binding lipoprotein); This protein is a component of an oligopeptide permease, a binding protein-dependent transport system. This APP system can completely substitute for the OPP system in both sporulation and genetic competence, though, unlike OPP, is incapable of transporting tripeptides. Probably responsible for the translocation of the substrate across the membrane (By similarity); Belongs to the binding-protein-dependent transport system permease family. OppBC subfamily.

Oligopeptide ABC transporter (permease); Part of the binding-protein-dependent transport system for oligopeptides; probably responsible for the translocation of the substrate across the membrane. Also required for sporulation and competence.
 
 0.932
natA
Na+ ABC efflux transporter (ATP-binding protein); Part of an ABC transporter that catalyzes ATP-dependent electrogenic sodium extrusion; Belongs to the ABC transporter superfamily.
 
    
0.897
ykfD
Putative cell wall oligopeptide ABC transporter (ATP binding protein); Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative transporter; Belongs to the ABC transporter superfamily.
