| Description: | 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. There are several different types of transmembrane ATPases, which can differ in function (ATP hydrolysis and/or synthesis), structure (e.g., F-, V- and A-ATPases, which contain rotary motors) and in the type of ions they transport [, ]. The different types include:F-ATPases (F1F0-ATPases), which are found in mitochondria, chloroplasts and bacterial plasma membranes where they are the prime producers of ATP, using the proton gradient generated by oxidative phosphorylation (mitochondria) or photosynthesis (chloroplasts).V-ATPases (V1V0-ATPases), which are primarily found in eukaryotic and they function as proton pumps that acidify intracellular compartments and, in some cases, transport protons across the plasma membrane []. They are also found in bacteria [].A-ATPases (A1A0-ATPases), which are found in Archaea and function like F-ATPases, though with respect to their structure and some inhibitor responses, A-ATPases are more closely related to the V-ATPases [, ].P-ATPases (E1E2-ATPases), which are found in bacteria and in eukaryotic plasma membranes and organelles, and function to transport a variety of different ions across membranes.E-ATPases, which are cell-surface enzymes that hydrolyse a range of NTPs, including extracellular ATP.P-ATPases (also known as E1-E2 ATPases) () are found in bacteria and in a number of eukaryotic plasma membranes and organelles []. 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.This family represents the P-type ATPase responsible for translocating calcium ions across the golgi membrane of fungi and animals [, ] and is of particular importance in the sarcoplasmic reticulum of skeletal and cardiac muscle in vertebrates []. The calcium P-type ATPases have been characterised as Type IIA based on a phylogenetic analysis which distinguishes this group from the Type IIB PMCA calcium pump [] described in . A separate analysis divides Type IIA into sub-types, SERCA and PMR1 [] the former of which is described in . | Short Name: | P-type_ATPase_IIA_PMR1 |
