[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 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 کاملAccessible atomic structures from sub-micron protein crystals.
New instruments and techniques expand the reach of crystallography, making it more efficient and/or accessible to the greater scientific community. However, despite technological improvements, crystallography still faces outstanding challenges. As an example, structure determination from sub-micron crystals remains largely out of reach for conventional crystallography. In this issue of Acta Cry...
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...
