Applications of the second virial coefficient: protein crystallization and solubility
A number of citations in the article by Wilson & DeLucas [(2014). Acta Cryst. F70, 543-554] are corrected.
متن کاملSelecting Temperature for Protein Crystallization Screens Using the Temperature Dependence of the Second Virial Coefficient
Protein crystals usually grow at a preferable temperature which is however not known for a new protein. This paper reports a new approach for determination of favorable crystallization temperature, which can be adopted to facilitate the crystallization screening process. By taking advantage of the correlation between the temperature dependence of the second virial coefficient (B(22)) and the so...
متن کاملWhy is the osmotic second virial coefficient related to protein crystallization?
A molecular basis is presented for characterizing the osmotic second virial coefficient, B 22 , of dilute protein solutions, which provides a measure of the nature of protein—protein interactions and has been shown to be correlated with crystallization behavior. Experimental measurements of the second virial coefficient of lysozyme and bovine a-chymotrypsinogen A were performed by static light ...
متن کاملAb initio study of the second virial coefficient protein — protein on the basis of intermolecular potential energy surface
Intermolecular potential energy surface (IPS) for protein — protein has been examined using RHF, DFT-B3LYPand MP2 levels of theory with 6-31G, 6-31G* basis sets. A number of basis sets were used in order to evaluatethe basis set effects, at all three levels of theory, basis sets has significant effects on the calculated potentialenergy curves (including position, depth and width of the potentia...
متن کاملOn the Relationship between the Solubility of Proteins and the Osmotic Second Virial Coefficient
A relationship between the osmotic second virial coefficient of proteins in aqueous salt solutions, the solubility of proteins in these solutions and the salt concentration is presented. The model developed considers that the solid-liquid equilibrium is established with neutral protein molecules and that the relationship between the protein solubility and the salt concentration follows Cohn's e...
