IntEnz Enzyme Nomenclature


Accepted name:
ABC-type dipeptide transporter
Other names:
dipeptide transporting ATPase
dipeptide ABC transporter
dppBCDF (gene names)
Systematic name:
ATP phosphohydrolase (ABC-type, dipeptide-transporting)



ATP-binding cassette (ABC) type transporter, characterized by the presence of two similar ATP-binding domains/proteins and two integral membrane domains/proteins. A bacterial enzyme that interacts with an extracytoplasmic substrate binding protein and mediates the uptake of di- and tripeptides. The enzyme from Pseudomonas aeruginosa can interact with five different substrate binding proteins.
