WebMar 9, 2024 · X-ray crystallography is a powerful technique for determining the 3D structure of membrane proteins; however, practitioners face a variety of unique challenges, including expression difficulties, the instability of membrane proteins upon detergent extraction, and a lower probability of crystallization. The basic driving force for protein crystallization is to optimize the number of bonds one can form with another protein through intermolecular interactions. These interactions depend on electron densities of molecules and the protein side chains that change as a function of pH. The tertiary and quaternary structure of proteins are determined by intermolecular interactions between the amino acids’ side groups, in which the hydrophilic groups are usually facing outwards to the sol…
