Characterization of a mutant bacillus thuringiensis delta endotoxin with enhanced stability and toxicity

The centrally located a-helix 5 of Bacillus thuringiensis d-endotoxins is critical for insect toxicity through ion-channel formation. We analyzed the role of the highly conserved residue Histidine 168 (H168) using molecular biology, electrophysiology and biophysical techniques. Toxin H168R was ~3-fo...
