Abstract
This article describes a practical experiment for teaching basic spectroscopic techniques to introduce the topic of protein conformational change to students in the field of molecular biology, biochemistry, or structural biology. The spectroscopic methods employed in the experiment are absorbance, for protein concentration measurements, and fluorescence and circular dichroism, for probing protein conformational changes.

## Abstract A simple method is presented for the analysis of protein conformational changes based on the comparison of torsion angles defined by four consecutive CΞ± atoms. The technique was applied successfully to proteins that undergo hinge motion and shear motion. In the case of both MBP and LAO,
## Abstract We have assembled a nonredundant set of 144 proteinβprotein complexes that have highβresolution structures available for both the complexes and their unbound components, and for which dissociation constants have been measured by biophysical methods. The set is diverse in terms of the bi
