Reaction: ATP + H2O + phosphonate-[phosphonate-binding protein][side 1] = ADP + phosphate + phosphonate[side 2] + [phosphonate-binding protein][side 1]
Other name(s): phosphonate-transporting ATPase (ambiguous)
Systematic name: ATP phosphohydrolase (ABC-type, phosphonate-importing)
Comments: An ATP-binding cassette (ABC) type transporter, characterized by the presence of two similar ATP-binding domains/proteins and two integral membrane domains/proteins. The enzyme, found in bacteria, interacts with an extracytoplasmic substrate binding protein and mediates the import of phosphonate and organophosphate anions.
