Crystal soaking vs co-crystallization
WebTo address this problem, we present a combined co-crys- tallization and peptide-soaking approach to obtain crystals for any 14-3-3 –peptide complex that may exhibit difficulties when crystallizing under our optimized ‘sigma’ conditions. WebCo-crystals are multi-component crystals based on hydrogen bonding interactions without the transfer of hydrogen ions to form salts; this is an important feature, since Bronsted …

WebFeb 20, 2013 · In principle there are four methods to include the substrate into the crystallization trials: 1) co-crystallization 2) ligand soaking 3) micro or macro seeding 4) endogenously bound ligands. The first method is co-crystallization. Here, normally the substrate is added prior to crystallization to the protein solution. WebMay 28, 2024 · Soaking of macromolecular crystals allows the formation of complexes via diffusion of molecules into a preformed crystal for structural analysis. Soaking offers …
WebMany other methods exist in order to produce cocrystals. Crystallizing with a molar excess of one cocrystal former may produce a cocrystal by a decrease in solubility of that one … WebApr 12, 2012 · The debate generated strong consensus on the need to define cocrystals more broadly and to classify them like salts. It was also concluded that the diversity of API crystal forms makes it difficult to classify solid forms …

Co-crystallization involves mixing of the free protein in solution with the small molecule prior to crystallization, which allows the …
WebAn alternative approach for fragment screening is the co-crystallization of the protein in the presence of the fragment. This method is resource-intensive since each compound requires a separate crystallization experiment. Thus, co-crystallization is commonly used when fragment soaking either affects crystal stability or fails to identify any hits.
