A description of fundamental and applied aspects of the usefulness of computations when approaching protein-protein interactions, this book incorporates different views of the same biochemical problem from sequence to structure to energetics. It covers protein-protein interaction prediction and dynamics, design, drug design for inhibition, and uses for predicting function. The text provides an overview of the topic with general chapters understandable by students and junior researches in this area, while also providing advanced material for more specialized readers. The chapters detail the complexity of protein interaction studies and inform readers of potential caveats that might be involved.
