IUBMB Enzyme Nomenclature

EC 3.6.3.27

Accepted name: phosphate-transporting ATPase

Reaction: ATP + H2O + phosphateout = ADP + phosphate + phosphatein

Other name(s): ABC phosphate transporter

Systematic name: ATP phosphohydrolase (phosphate-importing)

Comments: ABC-type (ATP-binding cassette-type) ATPase, characterised by the presence of two similar ATP-binding domains. Does not undergo phosphorylation during the transport process. A bacterial enzyme that imports phosphate anions.
