A snapshot from the dynamics simulations of a tri-NAG oxocarbenium ion intermediate bound to barley chitinase. An arrow marks the α face of the oxocarbenium ion, which will result in inversion of the anomeric configuration upon nucleophilic attack by water. Ser 120 and Glu 89 are positioned to coordinate with this water molecule as shown with dashed lines. Glu 67 forms a hydrogen bond with HO6′.
