High-pressure crystallography.
Since the late 1950's, high-pressure structural studies have become increasingly frequent, following the inception of opposed-anvil cells, development of efficient diffractometric equipment (brighter radiation sources both in laboratories and in synchrotron facilities, highly efficient area detectors) and procedures (for crystal mounting, centring, pressure calibration, collecting and correctin...
متن کاملHigh-pressure crystallography of periodic and aperiodic crystals
More than five decades have passed since the first single-crystal X-ray diffraction experiments at high pressure were performed. These studies were applied historically to geochemical processes occurring in the Earth and other planets, but high-pressure crystallography has spread across different fields of science including chemistry, physics, biology, materials science and pharmacy. With each ...
متن کاملHigh-pressure protein crystallography of hen egg-white lysozyme
Crystal structures of hen egg-white lysozyme (HEWL) determined under pressures ranging from ambient pressure to 950 MPa are presented. From 0.1 to 710 MPa, the molecular and internal cavity volumes are monotonically compressed. However, from 710 to 890 MPa the internal cavity volume remains almost constant. Moreover, as the pressure increases to 950 MPa, the tetragonal crystal of HEWL undergoes...
متن کاملProbing substates in sperm whale myoglobin using high-pressure crystallography.
Pressures in the 100 MPa range are known to have an enormous number of effects on the action of proteins, but straightforward means for determining the structural basis of these effects have been lacking. Here, crystallography has been used to probe effects of pressure on sperm whale myoglobin structure. A comparison of pressure effects with those seen at low pH suggests that structural changes...
متن کاملHigh-pressure protein crystallography and NMR to explore protein conformations.
High-pressure methods for solving protein structures by X-ray crystallography and NMR are maturing. These techniques are beginning to impact our understanding of thermodynamic and structural features that define not only the protein's native conformation, but also the higher free energy conformations. The ability of high-pressure methods to visualize these mostly unexplored conformations provid...
