Supramolecular Enzyme Organization: Quaternary Structure and Beyond provides a comprehensive discussion of enzyme interactions. It attempts to place conceptually related phenomena in a common perspective by first scrutinizing enzyme interactions at the quaternary level and then moving on towards higher orders of organization. The book begins with a discussion of the hierarchy of enzymes, covering the structure of monomeric enzymes, enzyme structures beyond the monomeric stage, and protein-protein interactions. Separate chapters cover the chemistry of protein associations; the quaternary structure of enzymes; multienzyme systems; multienzyme complexes and conjugates; the association of enzymes with cellular structures; and metabolite compartmentation. The final chapters discuss trends in the study of enzyme systems and the dialectics of enzymology. This book is intended, not for the specialist, who knows much more about the individual questions than the text offers, but rather for the general biochemical reader interested in enzyme organization. There is practically no mathematics involved. Instead, quite elementary things are described, so that students and biologists with less background knowledge on enzymes will be able to join in.
