Function
function
Part of the ABC transporter DppABCDF involved in the uptake of various di/tripeptides (PubMed:25338022).
Is also involved in the uptake of phaseolotoxin, a toxic tripeptide inhibiting the enzyme ornithine carbamoyltransferase (PubMed:25338022).
Responsible for the translocation of the substrate across the membrane (Probable)

Interaction
Subunit
The complex is composed of two ATP-binding proteins (DppD and DppF), two transmembrane proteins (DppB and DppC) and a solute-binding protein (DppA1-A5) (PubMed:25338022).
Five orthologous SBPs (DppA1-A5) are present in P.aeruginosa, which increases the substrate specificity of the DppBCDF transporter (PubMed:25338022).
