Accepted name: P-type phospholipid transporter
Reaction: ATP + H2O + phospholipid[side 1] = ADP + phosphate + phospholipid[side 2]
Other name(s): Mg2+-ATPase (ambiguous); flippase (ambiguous); aminophospholipid-transporting ATPase (ambiguous); phospholipid-translocating ATPase (ambiguous); phospholipid-transporting ATPase (ambiguous)
Systematic name: ATP phosphohydrolase (P-type, phospholipid-flipping)
Comments: A P-type ATPase that undergoes covalent phosphorylation during the transport cycle. Different forms of the enzyme move phospholipids such as phosphatidylcholine, lyso-phosphatidylcholine, phosphatidylserine, phosphatidylethanolamine, phosphatidyglycerol, sphingomyelin and glucosylceramide from one membrane face to the other (‘flippase’).
