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

ddpAD,D-dipeptide ABC transporter periplasmic binding protein; Part of the ABC transporter complex DdpABCDF, which is probably involved in D,D-dipeptide transport; Belongs to the bacterial solute-binding protein 5 family. (516 aa)    
Predicted Functional Partners:
ddpD
D,D-dipeptide ABC transporter ATPase; 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.
 
 0.997
ddpC
D,D-dipeptide ABC transporter permease; 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; Belongs to the binding-protein-dependent transport system permease family. OppBC subfamily.
 
 0.996
ddpB
D,D-dipeptide ABC transporter permease; 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; Belongs to the binding-protein-dependent transport system permease family. OppBC subfamily.
 
 0.995
ddpX
D-ala-D-ala dipeptidase, Zn-dependent; Catalyzes hydrolysis of the D-alanyl-D-alanine dipeptide. May have a role in cell-wall turnover.
 
    0.994
ddpF
D,D-dipeptide ABC transporter ATPase; 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
Putative ABC transporter permease; 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. Belongs to the bacterial solute-binding protein 5 family.
 
  
0.946
sapC
Antimicrobial peptide transport ABC transporter permease; Part of a putrescine export transport system, does not play a role in resistance to antimicrobial peptides.
  
 0.915
sapB
Antimicrobial peptide transport ABC transporter permease; Part of a putrescine export transport system, does not play a role in resistance to antimicrobial peptides.
  
 0.915
dppB
Dipeptide/heme ABC transporter permease; Part of the binding-protein-dependent transport system for dipeptides; probably responsible for the translocation of the substrate across the membrane; Belongs to the binding-protein-dependent transport system permease family. OppBC subfamily.
 
 0.903
nikB
Nickel ABC transporter permease; Involved in a nickel transport system, probably translocates nickel through the bacterial inner membrane.
