Abstract
Here, we review recent studies aimed at defining the importance of quaternary structureto a model oligomeric enzyme, dihydrodipicolinate synthase. This will illustrate thecomplementary and synergistic outcomes of coupling the techniques of analytical ultracentrifugationwith enzyme kinetics, in vitro mutagenesis, macromolecular crystallography,small angle X-ray scattering, and molecular dynamics simulations, to demonstratethe role of subunit self-association in facilitating protein dynamics and enzyme function.This multitechnique approach has yielded new insights into the molecular evolution ofprotein quaternary structure.
