IntEnz Enzyme Nomenclature


Accepted name:
P-type phospholipid transporter
Other names:
aminophospholipid-transporting ATPase [ambiguous]
flippase [ambiguous]
phospholipid-transporting ATPase
Systematic name:
ATP phosphohydrolase (P-type, phospholipid-flipping)



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'). Formerly EC and EC
