Cleavage of Elongation Factor G into Compact Domains

Abstract
A limited trypsinolysis of native [bacterial] elongation factor G results in the formation of 2 large fragments resistant to further proteolysis. The fragments were isolated in homogeneous state in conditions when their native structure is retained. According to circular dichroism and scanning calorimetry data, the formed fragments retain the stability and compact structure that they had in the whole protein.
