摘要：

Information about the interaction forces at the contact regions between fumarase subunits is obtained from kinetic and structural studies of dissociation and reassociation. In dilute urea solutions an equilibrium between tetramers and dimers is established. No appreciable unfolding of the individual subunits is observed in these conditions.
