Mechanism and structure of the plant plasma membrane Ca{sup 2+}-ATPase

Objectives of this project were the following: development of an enriched preparation of the red beet plasma membrane Ca{sup 2+} ATPase in order to develop a procedure for detergent solubilization of the enzyme from the membrane using detergents, resolution by a method which could be upscaled for batch isolation, and then reconstitution into liposomes to allow characterization of Ca{sup 2+} transport by the purified enzyme and; characterization of the reaction mechanism for the coupling of nucleoside triphosphate hydrolysis to Ca{sup 2+} transport as mediated by the plasma membrane Ca{sup 2+} ATPase
