Multiple unfolding states of glutathione transferase from Physa acuta (Gastropada: Physidae)

Biochemical and Biophysical Research Communications, 2006
The equilibrium unfolding of the major Physa acuta glutathione transferase isoenzyme (P. acuta GST(3)) has been performed using guanidinium chloride (GdmCl), urea, and acid denaturation to investigate the unfolding intermediates. Protein transitions were monitored by intrinsic fluorescence. The results indicate that unfolding of P.
