Fig. 1. Ribbon diagram of the protein structure of trans-cinnamoyl-subtilisin in acetonitrile. The catalytic triad (Asp-32, His-64, and Ser-221) is portrayed as sticks. The cinnamoyl group is shown in black. Water molecules and acetonitrile molecules are depicted by balls-and-sticks, with the nitrogen atoms of acetonitrile in black.
