   Sammanfattning : Magnetic relaxation dispersion measurements have been performed on aqueous protein solutions to study the dynamics of waters in the proton transport channel of bacteriorhodopsin and the self-association of the proteins BPTI, lysozyme and beta-lactoglobulin. The measurements have focused on the bulk relaxation rates, R1 and R2, of three water nuclei 1H, 2H and 17O that are coupled to the protein environments by exchange and therefore report on properties such as the protein tumbling and dynamics of internal waters.
