Electron 3D crystallography of protein crystals for visualization of charges
Electron crystallography has the potential to analyze crystals of membrane proteins and macromolecular complexes too small or too thin for X-ray crystallography, as electrons are scattered 4 5 orders of magnitude more strongly than X-rays. Electron crystallography yields Coulomb potential maps, rather than electron density maps as X-rays do, providing information on charged states of amino-acid...
متن کاملElectron crystallography of ultrathin 3D protein crystals: atomic model with charges.
Membrane proteins and macromolecular complexes often yield crystals too small or too thin for even the modern synchrotron X-ray beam. Electron crystallography could provide a powerful means for structure determination with such undersized crystals, as protein atoms diffract electrons four to five orders of magnitude more strongly than they do X-rays. Furthermore, as electron crystallography yie...
متن کاملElectron Crystallography of Two-Dimensional Crystals of Membrane Proteins.
Electron microscopy has become a powerful technique, along with X-ray crystallography and nuclear magnetic resonance spectroscopy, to study the three-dimensional structure of biological molecules. It has evolved into a number of methods dealing with a wide range of biological samples, with electron crystallography of two-dimensional crystals being so far the only method allowing data collection...
متن کاملCrystallography of Icosahedral Crystals
The crystallography of icosahedral crystals is constructed. The actual three-dimensional crystal is represented by a three-dimensional cut in a regular six-dimensional periodic crystal with symmetry described by a six-dimensional space group, and the positions of atoms correspond to an arrangement of hypersurface segments. The resulting crystal can not in general be viewed as a space-filling ar...
متن کاملAtomic electron tomography: 3D structures without crystals.
Crystallography has been fundamental to the development of many fields of science over the last century. However, much of our modern science and technology relies on materials with defects and disorders, and their three-dimensional (3D) atomic structures are not accessible to crystallography. One method capable of addressing this major challenge is atomic electron tomography. By combining advan...
