nuclear magnetic resonance analyses have been made of the individual hydrogen-deuterium exchange rates of tryptophan indole n-1 hydrogens in native lysozyme and its chemically modified derivatives including lysozyme with an ester cross-linkage between glu-35 and trp-108 , lysozyme with an internal amide cross-linking between the epsilon-amino group of lys-13 and the alpha-carboxyl group of leu-129 , and lysozyme with the beta-aspartyl sequence at asp-101 .
