Abstract
The membrane-bound proton transporting ATPase/ ATP-synthase of bacteria, mitochondria and chloroplasts catalyses the reversible synthesis/hydrolysis of ATP from ADP and Pi. The mitochondrial enzyme is the major source of cellular ATP in the absence of photosynthesis. It is believed that the electro-chemical gradient produced during electron transport is utilised by the ATPase during ATP synthesis in a process involving proton translocation. The enzyme has a requirement for a divalent cation for activity. Normally this requirement is fulfilled by magnesium ions although the chloroplast (Vambutas and Racker 1965) and pea mitochondrial enzymes are also activated by calcium ions (Grubmeyer and Spencer 1979).
