Phospholipid-translocating ATPase
From Wikipedia, the free encyclopedia
In enzymology, a phospholipid-translocating ATPase (EC 3.6.3.1) is an enzyme that catalyzes the chemical reaction
- ATP + H2O + phospholipidin ADP + phosphate + phospholipidout
The 3 substrates of this enzyme are ATP, H2O, and phospholipid, whereas its 3 products are ADP, phosphate, and phospholipid.
This enzyme belongs to the family of hydrolases, specifically those acting on acid anhydrides acting on acid anhydrides to catalyse transmembrane movement of substances. The systematic name of this enzyme class is ATP phosphohydrolase (phospholipid-flipping). Other names in common use include Mg2+-ATPase, flippase, and aminophospholipid-transporting ATPase.
