[4] X-Ray Diffraction of Protein Crystals
The X-ray study of protein crystals is a difficult and highly specialized field. Eventually, when the structure of a few proteins has been unraveled, the results will be of vital interest to ensytiologists, since they should give information about the spatial arrangement of the “active site” of the enzyme. But meanwhile X-ray methods will have only a secondary interest for enzymologists. The eq...
متن کاملX-Ray Topography
Certain commercial entities, equipment, or materials may be identified in this document in order to describe an experimental procedure or concept adequately. Such identification is not intended to imply recommendation or endorsement by the National Institute of Standards and Technology, nor is it intended to imply that the entities, materials, or equipment are necessarily the best available for...
متن کاملFemtosecond X-ray diffraction from two-dimensional protein crystals
X-ray diffraction patterns from two-dimensional (2-D) protein crystals obtained using femtosecond X-ray pulses from an X-ray free-electron laser (XFEL) are presented. To date, it has not been possible to acquire transmission X-ray diffraction patterns from individual 2-D protein crystals due to radiation damage. However, the intense and ultrafast pulses generated by an XFEL permit a new method ...
متن کاملCompressibility of lysozyme protein crystals by X-ray diffraction.
Single-crystal high-pressure X-ray diffraction studies on the protein crystals of orthorhombic and tetragonal hen egg-white lysozyme polymorphs were carried out using a Merrill-Bassett diamond-anvil cell, image-plate detector and synchrotron radiation. The orthorhombic crystal has been squeezed to 85.5% of its ambient pressure volume at about 1.0 GPa; the crystal compresses anisotropically, and...
متن کاملCoherent X-ray diffractive imaging of protein crystals.
The technique of coherent X-ray diffraction imaging (CXDI) has recently shown great promise for the study of inorganic nanocrystals. In this work the CXDI method has been applied to the study of micrometer-size protein crystals. Finely sampled diffraction patterns of single crystals were measured and iterative phase-retrieval algorithms were used to reconstruct the two-dimensional shape of the ...
