Aggregation of binding protein from rat nerve.
Leucine-binding protein described in an earlier paper was examined to characterize the dynamic properties of the system. Leucine-binding protein assembles into a large protein polymer or complex (greater than 302,000 daltons). Colchicine reduces and Mg2+ increases the amount of polymer formed. Trypsin destroys the isolated polymer but RNAase and collagenase do not. Mg2+-ATPase activity is present in the polymer fraction. The formation of the large complex suggests a quickly adaptable structure capable of responding to ionic and environmental conditions.
