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. The enzyme moves phospholipids such as phosphatidylcholine, phosphatidylserine, and phosphatidylethanolamine from one membrane face to the other ('flippase'). Formerly EC EC
