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

sapCAntimicrobial peptide transport ABC transporter permease; Part of a putrescine export transport system, does not play a role in resistance to antimicrobial peptides. (296 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
sapB
Antimicrobial peptide transport ABC transporter permease; Part of a putrescine export transport system, does not play a role in resistance to antimicrobial peptides.
 
 0.999
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.
 
 
 0.998
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.
  
  0.984
dppF
Dipeptide/heme ABC transporter ATPas; Part of the binding-protein-dependent transport system for dipeptides. Probably responsible for energy coupling to the transport system; Belongs to the ABC transporter superfamily.
 
  
  0.967
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.
  
  0.963
nikD
Nickel ABC transporter ATPase; Part of the ABC transporter complex NikABCDE involved in nickel import. Responsible for energy coupling to the transport system. Belongs to the ABC transporter superfamily. Nickel importer (TC 3.A.1.5.3) family.
  
  0.956
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.
  
  0.952
oppD
Oligopeptide ABC transporter ATPase; Part of the binding-protein-dependent transport system for oligopeptides. Probably responsible for energy coupling to the transport system.
