Abstract：
:Recent advances in neutron and X-ray sources and instrumentation, new and improved scattering techniques, and molecular biology techniques, which have permitted facile preparation of samples, have each led to new opportunities in using small-angle scattering to study the conformations and interactions of biological macromolecules in solution as a function of their properties. For example, new instrumentation on synchrotron sources has facilitated time-resolved studies that yield insights into protein folding. More powerful neutron sources, combined with molecular biology tools that isotopically label samples, have facilitated studies of biomolecular interactions, including those involving active enzymes.

The archetypical ACT domain is the C-terminal regulatory domain of 3-phosphoglycerate dehydrogenase (3PGDH), which folds with a ferredoxin-like betaalphabetabetaalphabeta topology. A pair of ACT domains form an eight-...
