This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the transport of phospholipids (Potential). Seems to be involved in ribosome assembly. ATP + H2O + phospholipidSide 1 = ADP + phosphate + phospholipidSide 2. Interacts with CDC50. Present with 606 molecules/cell in log phase SD medium. Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IV subfamily.
