Bacillus thuringiensis CryIA(a) insecticidal toxin: crystal structure and channel formation.

Journal of molecular biology - 1 Dec 1995

Grochulski P, Masson L, Borisova S, Pusztai-Carey M, Schwartz J L, Brousseau R, Cygler M

Abstract excerpt

The activated 65 kDa lepidopteran-specific CryIA(a) toxin from the commercially most important strain Bacillus thuringiensis var. kurstaki HD-1 has been investigated by X-ray diffraction and for its ability to form channels in planar lipid bilayers. Its three-dimensional structure has been determined by a multiple isomorphous replacement method and refined at 2.25 A resolution to an R-factor of 0.168 for data...
