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

sapBAntimicrobial peptide transport ABC transporter permease; Part of a putrescine export transport system, does not play a role in resistance to antimicrobial peptides. (321 aa)    
Predicted Functional Partners:
sapF
Antimicrobial peptide ABC transporter ATPase; Part of a putrescine export transport system, does not play a role in resistance to antimicrobial peptides. Does not stimulate K(+) uptake ability of TrkH on its own, but increases K(+) uptake by 20% in the presence of SapD; has no effect of TrkG ; Belongs to the ABC transporter superfamily.
 
 0.999
sapD
Antimicrobial peptide ABC transporter ATPase; Part of a putrescine export transport system, does not play a role in resistance to antimicrobial peptides. Stimulates K(+)-uptake proteins TrkG and TrkH to import K(+), may act via ATP-binding rather than ATP hydrolysis.
 
 0.999
sapC
Antimicrobial peptide transport ABC transporter permease; Part of a putrescine export transport system, does not play a role in resistance to antimicrobial peptides.
 
 0.999
sapA
Antimicrobial peptide transport ABC transporter periplasmic binding protein; Not part of a putrescine export system. Very similar to a S.typhimurium protein implicated in antimicrobial peptide resistance, but the SapBCDF operon in E.coli is implicated in putrescine export.
 
 0.999
ddpA
D,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.
  
 0.915
dppC
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.
 
  
  0.897
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.
 
  
  0.895
gsiD
Glutathione ABC transporter permease; Part of the ABC transporter complex GsiABCD involved in glutathione import. Probably responsible for the translocation of the substrate across the membrane.
 
  
  0.893
nikC
Nickel ABC transporter permease; Involved in a nickel transport system, probably translocates nickel through the bacterial inner membrane.
 
  
  0.893
dppD
Dipeptide/heme ABC transporter ATPas; Part of the binding-protein-dependent transport system for dipeptides. Probably responsible for energy coupling to the transport system.
