CRYSTAL STRUCTURE OF INSECTICIDAL -ENDOTOXIN FROM BACILLUS THURINGIENSIS AT 2.5 A RESOLUTION

CRY3Bb1 BELONGS TO THE "CRY" FAMILY OF DELTA-ENDOTOXINS, WHICH ARE PORE-FORMING INSECTICIDAL PROTEIN TOXINS CONTAINED IN THE CRYSTALLINE PARASPORAL INCLUSIONS OF BACILLUS THURINGIENSIS. THE SUBCLASS III IS TOXIC SPECIFICALLY TO COLEOPTERAN INSECTS, I.E., BEETLES. THEY FUNCTION BY BINDING TO MIDGUT EPITHELIAL CELLS AND INDUCE COLLOIDOSMOTIC LYSIS.
