Bacillus thuringiensis (Bt) is a unique bacterium in that it shares a common place with a
number of chemical compounds which are used commercially to control insects important to …

Since the first X-ray structure of Cry3Aa was revealed in 1991, numerous structures of B.
thuringiensis toxins have been determined and published. In recent years, functional studies …

Recent applications of biotechnology, especially genetic engineering, have revolutionized
crop improvement and increased the availability of valuable new traits. A current example is …

Bacillus thuringiensis (Bt) is a ubiquitous bacterium in soils, insect cadavers, phylloplane,
water, and stored grain, that produces several proteins, each one toxic to different biological …

Bacillus thuringiensis crystal proteins, well known to be toxic to certain insects but not
pathogenic to mammals, are used as insecticidal proteins in agriculture and forest …

Parasporin-2 is a protein toxin that is isolated from parasporal inclusions of the Gram-
positive bacterium Bacillus thuringiensis. Although B. thuringiensis is generally known as a …

Bacillus thuringiensis strain A1462 produced two parasporal inclusion proteins with a
molecular mass of 88 kDa that were converted to 64-kDa toxins when activated by …

Pro-parasporin-1 is a parasporal inclusion protein of the non-insecticidal Bacillus
thuringiensis strain A1190. Cytotoxic fragments, named parasporin-1, were generated from …

Pore-forming toxins (PFTs) represent the largest known group of bacterial protein toxins to
date. Membrane insertion and subsequent pore-formation occurs after initial binding to cell …

Parasporin-1 is a novel non-insecticidal inclusion protein from Bacillus thuringiensis that is
cytotoxic to specific mammalian cells. In this study, we investigated the effects of parasporin …
