Abstract
- Abstract  InhA, a zinc metalloprotease secreted by Bacillus thuringiensis, specifically hydrolyzes antibacterial peptides produced by insect hosts. In this study, the inhA gene was cloned from B. thuringiensis 8010 using a pair of degenerate primers and the deduced 796 amino acid sequence showed a high degree of similarity with other InhA proteins in the Bacillus cereus group. The deduced amino acid sequence contained the zinc-binding motif (HEXXH), which is characteristic of the zinc-metalloprotease family. Additionally, the inhA gene was expressed in Escherichia coli BL21 (DE3). The expressed InhA protein was shown to be toxic to the third larvae of Plutella xylostella, contrary to preliminary study concerning the effect of InhA on Bombyx mori. This study provided insights into the potential of InhA for the biological control of certain lepidopteran insects. [ABSTRACT FROM AUTHOR]
