Domains II and III of Bacillus thuringiensis Cry1Ab toxin remain exposed to the solvent after insertion of part of domain I into the membrane
Bacillus thuringiensis produces insecticidal proteins named Cry toxins, that are used
commercially for the control of economical important insect pests. These are pore-forming
toxins that interact with different receptors in the insect gut, forming pores in the apical
membrane causing cell burst and insect death. Elucidation of the structure of the membrane-
inserted toxin is important to fully understand its mechanism of action. One hypothesis
proposed that the hairpin of α-helices 4–5 of domain I inserts into the phospholipid bilayer …

An error has been detected in the methodology description of “Insertion of Cry1Ab Mutant
Toxin into the BBMV.” The samples used in Western blot assays were not boiled. Instead,
they were incubated for 5 min at 37 C before loading into 10% SDS-PAGE. A new
supplemental Fig. S1 is presented.
