Binding of the CryIVD Toxin of Bacillus thuringiensis subsp. israelensis to Larval Dipteran Midgut Proteins.
Ligand-blotting experiments on dipteran brush border membrane vesicles (BBMVs) showed binding of CryIVD toxin of Bacillus thuringiensis subsp. israelensis to proteins of 148 kDa in Anopheles stephensi and of 78 kDa in Tipula oleracea, both species being susceptible to CryIVD. Binding of CryIVD with BBMVs of A. stephensi resulted in a stronger signal than with BBMVs of T. oleracea. Likewise, lar...
متن کاملTranscriptional regulation of the cryIVD gene operon from Bacillus thuringiensis subsp. israelensis.
The CryIVD protein is involved in the overall toxicity of the Bacillus thuringiensis subsp. israelensis parasporal inclusions and is one of the four major components of the crystals. Determination of the DNA sequence indicated that the cryIVD gene is the second gene of an operon which includes three genes. The first one encodes a 19-kDa polypeptide and has sequence homology with the orf1 gene o...
متن کاملOral toxicity of Bacillus thuringiensis subsp. israelensis to adult mosquitoes.
The solubilized entomotoxin of Bacillus thuringiensis subsp. israelensis killed adult male and female mosquitoes of several genera and of various physiological states when it was administered orally. Adult mosquito mortality was further influenced when the preparation was contained in sucrose solution. The potential implication for the control of adult mosquitoes is discussed.

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
15 صفحه اولAntibacterial activity of Cyt1Aa from Bacillus thuringiensis subsp. israelensis.
Cyt1Aa is a delta-endotoxin protein that is produced by Bacillus thuringiensis subsp. israelensis. It is a membrane pore-forming toxin that is lethal to insect larvae and is broadly cytolytic to vertebrate as well as invertebrate cells. Cyt1Aa is produced as a protoxin of 27 kDa. Proteolytic activation results in a reduction of the molecular mass to approximately 23-24 kDa and a threefold incre...
