Higher-throughput approaches to crystallization and crystal structure determination.

چکیده
In recent times, there has been a large increase in the number of protein structures deposited in the Protein Data Bank. Structural genomics initiatives have contributed to this expansion through their focus on high-throughput structural determination. This has fuelled advances in many of the techniques in the pipeline from gene to protein to crystal to structure. These include ligation-independent cloning methods, parallel purification systems, robotic crystallization devices and automated methods of crystal identification, data collection and, in some cases, structure solution. Some of these advances are described and discussed briefly with an emphasis on activities in the York Structural Biology Laboratory through its participation in the Structural Proteomics in Europe consortium.

Comment on 'Protein isoelectric point as a predictor for increased crystallization screening efficiency'
MOTIVATION Increased efficiency in initial crystallization screening reduces cost and material requirements in structural genomics. Because pH is one of the few consistently reported parameters in the Protein Data Bank (PDB), the isoelectric point (pI) of a protein has been explored as a useful indirect predictor for the optimal choice of range and distribution of the pH sampling in crystalliza...
متن کاملFrom screen to structure with a harvestable microfluidic device
Advances in automation have facilitated the widespread adoption of high-throughput vapour-diffusion methods for initial crystallization screening. However, for many proteins, screening thousands of crystallization conditions fails to yield crystals of sufficient quality for structural characterization. Here, the rates of crystal identification for thaumatin, catalase and myoglobin using microfl...
متن کاملInvestigation of Different Stages of Aluminum Fluoride Crystal Growth
Crystallization of Aluminum fluoride at atmospheric pressure has been considered. Structure, size and shape of crystals formed during the crystallization process have been investigated. By applying the direct analysis method for the existed aluminum in solution, the aluminum fluoride nucleation process has been detected as a concentration valley at the outset of crystallization process. The...
متن کاملThe detection and subsequent volume optimization of biological nanocrystals
Identifying and then optimizing initial crystallization conditions is a prerequisite for macromolecular structure determination by crystallography. Improved technologies enable data collection on crystals that are difficult if not impossible to detect using visible imaging. The application of second-order nonlinear imaging of chiral crystals and ultraviolet two-photon excited fluorescence detec...
متن کاملCrystallization of RNA and RNA-protein complexes.
RNA plays a direct role in a variety of cellular activities, and in many cases its biological function is conferred by the RNA three-dimensional structure. X-ray crystallography is the method of choice for determining high resolution structures of large RNA molecules, and can also be used to compare related RNAs and identify conformational changes that may accompany biochemical activity. Howeve...
