IUBMB Enzyme Nomenclature


Accepted name: ABC-type glycerol 3-phosphate transporter

Reaction: ATP + H2O + sn-glycerol 3-phosphate-[glycerol 3-phosphate-binding protein][side 1] = ADP + phosphate + sn-glycerol 3-phosphate[side 2] + [glycerol 3-phosphate-binding protein][side 1]

Other name(s): glycerol-3-phosphate ABC transporter; glycerol-3-phosphate-transporting ATPase

Systematic name: ATP phosphohydrolase (ABC-type, sn-glycerol 3-phosphate-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. Does not undergo phosphorylation during the transport process. A bacterial enzyme that interacts with an extracytoplasmic substrate binding protein and mediates the high affinity uptake of glycerol 3-phosphate and various glycerophosphodiesters.
