The effect of enzyme-inhibitor complex formation on the hydration properties of the macromolecular moiety was investigated on the model system of a-chymotrypsin and its Ser-195 tosyl derivative. The primary (A-shell) hydration of the native and modified enzyme was compared by sorption measurements.
Subtilisin-A was colyophilized with various types of support materials, such as Amberlite IRC-50, Celite545, chitosan, DEAE-cellulose, DOWEX-1, zeolite, glass bead, and polystyrene. The colyophilized enzyme was used for the optical resolution of racemic l-phenylethylamine with 2,2,2-trifluoroethylbu
