Cross seeding protein crystallization
WebFigure 1 shows a schematic phase diagram for a protein crystallization experiment. At high protein and high precipitant concentrations, precipitation occurs as shown. ... Structure of arylamine N-acetyltransferase from Mycobacterium tuberculosis determined by cross-seeding with the homologous protein from M. marinum: triumph over adversity ... WebApr 1, 2003 · Seeding can be used to grow larger crystals or get them to grow singly, improve their diffraction quality, save protein, reduce long waits for spontaneous nucleation, and cross-seed other proteins. We foresee that the usefulness of seeding will continue in the era of high-throughput crystallography.

WebIn this paper, the first structure of TBNAT, determined using a lone crystal produced using cross-seeding with the homologous protein from M. marinum, is reported. Despite the similarity between the two enzymes (74% sequence identity), they show distinct physical and biochemical characteristics. ... Crystallization / methods Crystallography, X ... WebTo Control Crystal Size. Seeding is one of the most straightforward methods used to control supersaturation. During seeding, a small mass of crystals is added to a supersaturation in order to: Start the …
Seeding allows us to bypass the nucleation step (so long as we have just one starting crystal) and go straight to crystal growth. We can start with the tiny crystals that are useless in X-ray diffraction experiments and administer them to new crystallization drops. At the same time, we can change the … See more Experimental protein structures are essential to understanding the biology and, often enough, the pathology of organisms. And most protein structures are solved using X … See more Generating a protein crystal can be split into two steps: 1. Crystal nucleation. 2. Crystal growth. Crystal nucleation is the spontaneous … See more Let’s have a quick recap and go through the pros and cons of the five protein crystallization seeding methods discussed (Table 1). Table 1. Protein crystallization seeding methods pros and cons. See more These methods aren’t for the faint of heart since you have to disturb crystals that might be big enough already. It all depends on whether you’re up for a gamble. See more WebJun 28, 2007 · Vice-versa, when working with mutants or variants of a protein already crystallized, cross-seeding, with crystals of the native protein into drops containing the mutant or variant can be attempted ...
WebApr 21, 2014 · Protein crystallization involves two stages: nucleation and crystal growth. It is believed that the optimal conditions for these stages are different (García-Ruiz, 2003). Nucleation typically requires higher concentrations of the protein and precipitant. ... Cross-seeding proved to be a very efficient technique to deal with the problem, but ... WebWhen a ligand was added, these crystals grew. These were the ones that were with the best diffraction but took 4 months to grow. You can speed up the process considerably by using seeds of the apo-protein to seed the drops containing the holo-protein. To grow these crystals we had to use three optimizations: seeding, the cation Ni, and the ligand.
WebJan 8, 2024 · Here, we show that cross-linked protein crystals (CLPCs), which retain the crystal structure but are much more stable than non-cross-linked crystals, can also be used as a new type of seed for promoting protein crystallization. Seeding with CLPCs has effects on both the reproducibility and screening of protein crystals and could improve …
