Introduction to Protein Three-Dimensional Structure and the Architecture of Drug Binding Sites
Protein three-dimensional structures are precise and are stabilized by physical interactions between their atoms. These same interactions govern whether a particular drug molecule will interact with a particular protein, where it will bind and how strongly this binding will be. Over 50 years of protein crystallography have provided the structures of thousands of proteins many of which are in complexes with a drug molecule. Although each system is unique, there are interesting general rules that will be presented. These rules provide a simple physical view of interactions that are of fundamental importance to all of biology as well as of immense biomedical significance.
