Polyphosphate (polyP), synthesized by polyP kinase (PPK) using the terminal phosphate of ATP as substrate, performs important functions in every living cell. The present work reports on the relationship between polyP metabolism and bioinsecticide production in Bacillus thuringiensis subsp. israelensis (Bti). The ppk gene of Bti was cloned into vector pHT315(More)
It is not easy to manipulate biosynthetic genes of Bacillus thuringiensis since there is a powerful methyl-specific restriction system in this microorganism. In this study, a PCR-based system was used to delete polyphosphate kinase gene (ppk) of Bacillus thuringiensis israelensis (Bti) by replacing the wild-type gene with a cassette containing the apramycin(More)
