WebAbstract. Abstract Active transport of cations is achieved by a large family of ATP-dependent ion pumps, known as P-type ATPases. Various members of this family have been targets of structural and functional investigations for over four decades. Recently, atomic structures have been determined for Ca 2+ -ATPase by X-ray crystallography, which ... Primary transporters use energy to transport ions such as Na , K , and Ca across a cells membrane and can create concentration gradients. This transport can use ATP as an energy source or it can be used to generate ATP through methods such as the electron transport chain in plants. Transporters that use ATP convert the energy in ATP into potential energy in th…

Web-ATPase (P-type) [ edit] This enzyme belongs to the family of hydrolases, specifically those acting on acid anhydrides to catalyse transmembrane movement of substances. To be specific, the protein is a part of the P-type ATPase family. The systematic name of this enzyme class is ATP phosphohydrolase (H+ -exporting) .
