The talk will illustrate the use of hydrogen exchange methods to learn about biophysical properties and functional behaviors of protein molecules. Hydrogen exchange has been measured by older tritium exchange techniques, by 2D NMR, and most recently by mass spectrometry. Examples of applications will illustrate how each method provides specific advantages for different applications. Topics to be considered include how proteins fold, and how GroEL helps proteins to fold. Also recent progress in extending hydrogen exchange to the study of large and even insoluble protein systems using mass spectrometry will be shown.
