Abstract The crystalline proteins fromBac. thuringiensis of the third and fourth serotypes with a molecular weight of 130,000 have been isolated and carboxymethylated, and their amino acid compositions has been determined. The CM-proteins have been found to be labile in acid media (80% CF3COOH and 65% HCOOH). Conditions have been found for the cleavage of the CM-protein of the third serotype with cyanogen bromide. A BrCN fragment with a molecular weight of 16,000 has been isolated, the intensity of which in 5% polyacrylamide gel on scanning amounts to about half the intensity of the sum of all the fragments. The aminoacid composition of this fragment has been determined.
