Our predictions of residues with significant changes in methyl side- chain generalized order parameters upon ligand binding are in good agreement with the experimental data, and

This result will subsequently be seen to be due to a marked influence of pre-transitional effects associated with the N-SmA transition. Figure 3c sho~vs that a master curve can

The results of this work indicate that not only are there clear differences between our dry-hydroxide protocol and previous aqueous studies, but also that, while the trends between
