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

ddpBPart of the ABC transporter complex DdpABCDF, which is probably involved in D,D-dipeptide transport. Probably responsible for the translocation of the substrate across the membrane (340 aa)    
Predicted Functional Partners:
ddpD
Part of the ABC transporter complex DdpABCDF, which is probably involved in D,D-dipeptide transport . Probably responsible for energy coupling to the transport system.
 0.994
ddpC
Part of the ABC transporter complex DdpABCDF, which is probably involved in D,D-dipeptide transport. Probably responsible for the translocation of the substrate across the membrane
 0.994
ddpA
Part of the ABC transporter complex DdpABCDF, which is probably involved in D,D-dipeptide transport
 0.994
ddpF
Part of the ABC transporter complex DdpABCDF, which is probably involved in D,D-dipeptide transport . Probably responsible for energy coupling to the transport system.
 0.993
ygiS
Probably part of a deoxycholate transport system. Its expression in the presence of deoxycholate in a ygiS deletion mutant increases intracellular deoxycholate levels and decreases cell growth; higher expression in the presence of deoxycholate inhibits cell growth completely. Bile acid detergents such as deoxycholate are important for host defense against bacterial growth in the gall bladder and duodenum.
 
 0.899
ddpX
Catalyzes hydrolysis of the D-alanyl-D-alanine dipeptide. May have a role in cell-wall turnover
 
    0.881
dppD
Part of the binding-protein-dependent transport system for dipeptides. Probably responsible for energy coupling to the transport system
 
 0.847
dppC
Part of the binding-protein-dependent transport system for dipeptides; probably responsible for the translocation of the substrate across the membrane
 
 0.830
gsiD
Part of the ABC transporter complex GsiABCD involved in glutathione import. Probably responsible for the translocation of the substrate across the membrane
 
 
 0.812
nikC
Involved in a nickel transport system, probably translocates nickel through the bacterial inner membrane
 
 
 0.806
