RA   Bishop A.H., Bone E.J., Ellar D.J.;
RT   "Cloning of novel Bacillus thuringiensis delta-endotoxin.";
RL   Submitted (NOV-1994) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Promotes colloidosmotic lysis by binding to the midgut
CC       epithelial cells of insects.
CC   -!- DEVELOPMENTAL STAGE: The crystal protein is produced during sporulation
CC       and is accumulated both as an inclusion and as part of the spore coat.
CC   -!- MISCELLANEOUS: Toxic segment of the protein is located in the N-
CC       terminus.
CC   -!- SIMILARITY: Belongs to the delta endotoxin family. {ECO:0000305}.
