title: Subunit interactions in pig heart fumarase--II. Study of tetramer-dimer equilibrium in function of enzyme concentration and temperature.
abstract: The dissociation of pig fumarase tetramers into two dimers was studied as a function of temperature in the absence of denaturating agents. 1. At high temperatures a kinetical and structural study of dissociation and reassociation was performed. 2. At low temperatures fumarase dissociation was induced by limiting the enzyme concentration.
