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:
some 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

dppBDipeptide transport system permease protein dppb; 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 (308 aa)    
Predicted Functional Partners:
dppC
Dipeptide transport system permease protein dppc; 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
dppD
Dipeptide 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
 0.998
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
 0.996
oppC
Oligopeptide transport system permease protein oppc; 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
 
 0.936
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
    
 0.934
oppF
Oligopeptide abc transporter (atp-binding protein); Component of the oligopeptide permease, a binding protein- dependent transport system. Necessary for genetic competence but not sporulation. Probably responsible for energy coupling to the transport system
 
 0.931
ykfD
Putative cell wall oligopeptide abc transporter (atp binding protein); Belongs to the ABC transporter superfamily
 
 0.930
oppD
Oligopeptide abc transporter (atp-binding protein); Part of the binding protein-dependent transport system for oligopeptides. Probably responsible for energy coupling to the transport system. Required for sporulation and competence
 
 0.928
oppA
This protein is a component of the oligopeptide permease, a binding protein-dependent transport system, It binds peptides up to five amino acids long with high affinity. Also required for sporulation and competence
 
 0.900
appF
Peptide/nickel transport system atp-binding protein; 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 energy coupling to the transport system
