The crystal structures of four complexes of a signalling glycoprotein from goat (SPG-40) with oligosaccharides of different lengths have been determined. The structures of the complexes with GlcNAc3, GlcNAc4, GlcNAc5 and GlcNAc6 revealed the positions of these oligosaccharides in the carbohydrate-binding groove and provided insights into the binding mechanism of oligosaccharides to SPG-40.

The crystal structure of trypsin with a designed highly potent synthetic inhibitor has been determined at atomic resolution. The structure has revealed the precise nature of the interactions between the enzyme and the inhibitor molecules.
