WebApr 12, 2024 · This esterase has one mutation (S12A) on the catalytic triad to prevent the catalysis of substrate upon binding. The X-ray crystallography data of S12A provide understanding on the substrate specificity. Hence, the interactions between esterase and substrate could identify for possible drug discovery in the future. WebApr 7, 2024 · These x-ray crystallography structures each capture a snapshot of a dynamic protein structure in constant movement. By overlaying the distance and SASA scores across all 47 complexes, we observed that positions 2 and 9 are the ones most consistently close to the HLA molecule while also being secluded from the solvent.

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…
