We have developed a strategy for grafting a protein-protein interface based on the known crystal structure of a native ligand and receptor proteins in a complex. The key interaction residues at the ligand protein binding interface are transferred onto a scaffold protein so that the mutated scaffold

โฆ Synopsis
Biomolecular associations are governed by energetics that influence the stable or the transient nature of various bindings. Ab initio MO calculations on model systems representing a metal ion-carboxylate-water triad in proteins have been performed. Depending on the structural or catalytic role of the water molecule the geometry of interaction and consequently the energy of the ternary systems are found to be different.

Although interactions of proteins with glycosaminoglycans (GAGs), such as heparin and heparan sulphate, are of great biological importance, structural requirements for protein-GAG binding have not been well-characterised. Ionic interactions are important in promoting protein-GAG binding. Polyelectro
