    • The low temperature factor (ca. 20 Å) is another indication that only a single conformation of the benzylammonium ion is present in the binding pocket. Interestingly, molecular dynamics simulations on the benzylammonium-trypsin complex showed two different conformations of benzylammonium in the pocket. One exactly matches the electron density map of the benzylammonium-trypsin crystals and the other forms two hydrogen bonds with the carbonyl oxygen of Ser 190 and Asp 189 OG2.
