Abstract
The formation of vesicle-like structures (termed surfactosomes) and lamellar sheets from solutions containing ammonium perfluoroocanoate (APFO) is illustrated using conventional and cryo-transmission electron microscopy. It is shown how this detergent can be used for the solubilisation, reconstitution, and 2-D crystallisation of membrane proteins as demonstrated for the major protein of the membrane sector of the V-type H+-ATPase (16-kDa protein). Electron microscopical analysis of 2-D crystals of the 16-kDa protein (a = b = 13.0 ± 0.2 nm with γ = 90° and p4 projection symmetry) revealed a unit cell comprising four dimeric complexes of the 16-kDa protein the significance of which is discussed.
