Abstract: To evaluate the possible relationship between biological activity and structural stability in selected regions of the insulin molecule, we have analyzed the guanidine hydrochloride induced reversible unfolding of a series of mutant insulins using a combination of near- and far-UV circular dichroism (CD). The unfolding curves are reasonably described on the basis of a two-state denaturation scheme; however, the observation of subtle differences between near- and far-UV CD detected unfolding indicates that inter…
