Recently, two studies were published that examined the structure of the acid-β-glucosidase N370S mutant, the most common mutant that causes Gaucher disease. One study used the experimental tool of X-ray crystallography, and the other utilized molecular dynamics (MD). The two studies reinforced each other through the similarities in their findings, but each approach also added some unique information. Both studies report that the conformation of active site loop 3 changes, due to an altered hydrogen bonding network; however, the MD study produced additional data concerning the flexibility of loop 1 and the catalytic residues that are not observed in the other study.
