P-type ATPase, haloacid dehalogenase domain
IPR044492
Definition
This entry represents the haloacid dehalogenase domain (the catalytic domain) of P-type ATPases PMID:9584613. Transmembrane ATPases are membrane-bound enzyme complexes/ion transporters that use ATP hydrolysis to drive the transport of protons across a membrane. Some transmembrane ATPases also work in reverse, harnessing the energy from a proton gradient, using the flux of ions across the membrane via the ATPase proton channel to drive the synthesis of ATP. P-ATPases (also known as E1-E2 ATPases) ([ec:7.2.2.6]) 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+ [[cite:PMID:37838176], [cite:PMID:37264943]]. P-ATPases can be composed of one or two polypeptides, and can usually assume two main conformations called E1 and E2.
