Crystal soaking vs co-crystallization

Webprotein molecules in the lattice. Soaking inhibitors into preformed crystals is often used in iterative SADD and can provide certain advantages. The ability to stockpile a large number of crystals of known structure and diffraction quality and then soak them in compounds of interest can provide speed, convenience and reproducibility ... WebNov 3, 2016 · 1. Introduction. Obtaining protein–ligand complexes, the workhorse experiment in structure-based ligand design (SBLD), relies on two methods for achieving the prerequisite crystals: crystal soaking and co-crystallization (Hassell et al., 2007).Co-crystallization is achieved by adding the small molecule of interest to the protein prior to …

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. WebFeb 5, 2024 · The crystal structure of hemocyanin suggested a possibility that the hemocyanin crystals may encapsulate a guest molecule in their porous structure by both soaking and co-crystallization. In the present study, we evaluated the capability of hemocyanin crystals to encapsulate guest proteins and DNAs by these two methods …

WebJun 23, 2015 · Mixed cryoprotectants have been developed for the solubilization of ligands for crystallization of protein-ligand complexes and for crystal soaking. Low affinity lead compounds with poor solubility are problematic for structural studies. Complete ligand solubilization is required for co-crystallizat … WebIn this chapter we will consider the relative merits of various methods for modifying crystals, the restraints that the lattice may impose on the macromolecule, and the relative merits of soaking compared to co-crystallization.

WebCo-crystallization; Compared with soaking, protein-ligand co-crystallization usually requires more resources and time. However, it is often the best option when obvious conformational changes or crystal packing preclude other approaches.
