Direct methods for surface crystallography
In the most developed branches of crystallography, structure solution proceeds by two distinct steps: first, an approximate model of the structure is deduced directly from the measured data by an algorithm which assumes no preconceived model; second, a process of structure refinement simulates the experimental data for systematic variations of the parameters of such a model and determines a fin...
متن کاملAdvances in direct methods for protein crystallography.
Recent advances in ab initio direct methods have enabled the solution of crystal structures of small proteins from native X-ray data alone, that is, without the use of fragments of known structure or the need to prepare heavy-atom or selenomethionine derivatives, provided that the data are available to atomic resolution. These methods are also proving to be useful for locating the selenium atom...
متن کاملHigh-throughput methods for electron crystallography.
Membrane proteins play a tremendously important role in cell physiology and serve as a target for an increasing number of drugs. Structural information is key to understanding their function and for developing new strategies for combating disease. However, the complex physical chemistry associated with membrane proteins has made them more difficult to study than their soluble cousins. Electron ...
متن کاملDirect Methods of Structure Analysis in Polymer Crystallography
The use of direct phasing techniques, of the type familiar to small molecule x-ray crystallographers, for solving polymer crystal structures is discussed. Single crystal intensities from electron diffraction experiments are particularly useful, especially if the complete reciprocal lattice can be sampled. Furthermore, the analysis of powder or fiber x-ray data also is not precluded, especially ...
