Accepted name: ABC-type dipeptide transporter
Reaction: ATP + H2O + a dipeptide-[dipeptide-binding protein][side 1] = ADP + phosphate + a dipeptide[side 2] + [dipeptide-binding protein][side 1]
Other name(s): dipeptide transporting ATPase; dipeptide ABC transporter; dppBCDF (gene names)
Systematic name: ATP phosphohydrolase (ABC-type, dipeptide-transporting)
Comments: 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.
