The conformational stability of legumin and legumin-T was evaluated by
studying the equilibrium unfolding in the presence of guanidine hydro
chloride. The obtained thermodynamic parameters for the folding/unfold
ing-reaction (conformational stability Delta G(buffer)(o) at 25 degree
s C, its dependence on denaturant concentration m and the half denatur
ant concentration value [denaturant](1/2)) provided evidence that only
a rather small decrease in the conformational stability of the legumi
n after modification to legumin-T occurs under these conditions.
