Quaternary and tertiary structural transitions of (a) WT, (b) V30M, (c) L55P, and (d) V122I as a function of urea concentration. Tetramer dissociation followed by resveratrol binding (filled circles) and tertiary structural changes measured by tryptophan fluorescence (open squares, dashed line) have a very similar urea dependence, providing evidence that these equilibria are linked.
