Towards a compact and precise sample holder for macromolecular crystallography
Most of the sample holders currently used in macromolecular crystallography offer limited storage density and poor initial crystal-positioning precision upon mounting on a goniometer. This has now become a limiting factor at high-throughput beamlines, where data collection can be performed in a matter of seconds. Furthermore, this lack of precision limits the potential benefits emerging from au...
متن کاملA micro-patterned silicon chip as sample holder for macromolecular crystallography experiments with minimal background scattering
At low emittance synchrotron sources it has become possible to perform structure determinations from the measurement of multiple microcrystals which were previously considered too small for diffraction experiments. Conventional mounting techniques do not fulfill the requirements of these new experiments. They significantly contribute to background scattering and it is difficult to locate the cr...
متن کاملAutomation of sample mounting for macromolecular crystallography.
A standard sample holder and vial for cryocooled macromolecular crystals has been defined for use with robotic sample changers. This SPINE standard sample holder is a modified version, with added features and specifications, of sample holders in common use. In particular, the SPINE standard meets the precision required for automatic sample exchange and includes a cap that is identified by a two...
متن کاملMolProbity: all-atom structure validation for macromolecular crystallography
MolProbity is a structure-validation web service that provides broad-spectrum solidly based evaluation of model quality at both the global and local levels for both proteins and nucleic acids. It relies heavily on the power and sensitivity provided by optimized hydrogen placement and all-atom contact analysis, complemented by updated versions of covalent-geometry and torsion-angle criteria. Som...
متن کاملStrategies for macromolecular synchrotron crystallography.
Introduction During the past ten years the rate of protein structure determination by X-ray crystallography has risen about tenfold [1]. The use of synchrotron radiation was instrumental for this growth and the fraction of the results obtained this way increased from 28% in 1990 to 80% in 1999 (Figure 1). There are 52 synchrotron stations worldwide used for macromolecular crystallography, and t...
