Family relationships

Description

P-ATPases (also known as E1-E2 ATPases) (EC:3.6.3.-) are found in bacteria and in a number of eukaryotic plasma membranes and organelles [PMID: 9419228]. P-ATPases function to transport a variety of different compounds, including ions and phospholipids, across a membrane using ATP hydrolysis for energy. There are many different classes of P-ATPases, which transport specific types of ion: H+, Na+, K+, Mg2+, Ca2+, Ag+ and Ag2+, Zn2+, Co2+, Pb2+, Ni2+, Cd2+, Cu+ and Cu2+. P-ATPases can be composed of one or two polypeptides, and can usually assume two main conformations called E1 and E2.

Type IV ATPases have been shown to be involved in the transport of phospholipids [PMID: 9419228]. These ATPases are found only in eukaryotes.
