Abstract

Enhanced production of B. thuringiensis delta-endotoxin is achieved by employing the naturally occurring gene where an abbreviated 3'- and 5'-non-coding flanking region is employed. Particularly, the 3'-flanking does not extend past the downstream HincII cleavage site and the 5'-flanking region does not extend past the upstream HincII cleavage site. By having abbreviated flanking regions, enhanced production of the delta-endotoxin in E. coli is obtained.
