Abstract

The equilibrium denaturation pathway of Succinyl Con A exhibited three-state mechanism with the transition midpoints at 1 and 3 M GdnHCl and at 2.6 and 5 M urea. Unfolding resulted in stabilization of molten-globule (MG) like intermediate states at 2 M GdnHCl and 3 M urea. It was particularly interesting that state obtained at 3 M urea was functionally active.

Keywords: Succinylated Con A, Molten Globule like state, equilibrium denaturation, guanidine hydrochloride, urea
