Once you have the crystal, data collection …
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… WebUnderstanding Crystallography - Part 1: From Proteins to Crystals The Royal Institution 1.33M subscribers Subscribe 3.8K Share 236K views 8 years ago How can you determine the structure of a...
