| Structure of the ATP-Synthase from Chloroplasts and Mitochondria Studied by Electron Microscopy  | | | | Abstract
| The structure of the ATP-synthase, F 0 F,, from spinach chloroplasts and beef heart mitochon-dria has been investigated by electron microscopy with negatively stained specimens. The deter-gent-solubilized ATP-synthase forms string-like structures in which the F 0 parts are aggregated. In most cases, the F, parts are arranged at alternating sides along the string. The F 0 part has an approximate cylindrical shape with heights of 8.3 and 8.9 nm and diameters of 6.2 and 6.4 nm for the chloroplast and mitochondrial enzyme, respectively. The F, parts are disk-like structures with a diameter of about 11.5 nm and a height of about 8.5 nm. The F, parts are attached to the strings, composed of F n parts, in most cases, with their smallest dimension parallel to the strings. The stalk connecting F 0 and F, has a length of 3.7 nm and 4.3 nm and a diameter of 2.7 nm and 4.3 nm for the chloroplast and mitochondrial enzyme, respectively. | | | |
