Purification of a pore-forming peptide toxin, tolaasin, produced by Pseudomonas tolaasii 6264.
Tolaasin, a pore-forming peptide toxin, is produced by Pseudomonas tolaasii and causes brown blotch disease of the cultivated mushrooms. P. tolaasii 6264 was isolated from the oyster mushroom damaged by the disease in Korean. In order to isolate tolaasin molecules, the supernatant of bacterial culture was harvested at the stationary phase of growth. Tolaasin was prepared by ammonium sulfate pre...

بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...
In silico study of the ion channel formed by tolaasin I produced by Pseudomonas tolaasii.
A toxin produced by Pseudomonas tolaasii, tolaasin, causes brown blotch disease in mushrooms. Tolaasin forms pores on the cellular membrane and destroys cell structure. Inhibiting the ability of tolaasin to form ion channels may be an effective method to protect against attack by tolaasin. However, it is first necessary to elucidate the three-dimensional structure of the ion channels formed by ...
متن کاملPotentiation Effect Of 5FU by Fragaceatoxin C Pore-Forming Toxin in MCF-7 Cell Line
Introduction: Chemotherapy has been restricted due to the high-dose side effects. In the present study, acceleration of the chemotherapeutic drug (5FU) entrance into MCF-7 cells has been explored by using a recombinant form of Fragaceatoxin C (FraC) pore-forming toxin. Methods: In this experimental study, the gene for FraC toxin was order from a commercial source and was sub-cloned into pET28a...
متن کاملProduction of toxin by Clostridium botulinum type A strains cured by plasmids.
Twelve strains of Clostridium botulinum type A and seven strains of Clostridium sporogenes were screened for plasmids by agarose gel electrophoresis of cleared lysates of cells from 5 ml of mid-log-phase culture. Nine type A strains had one or more plasmids of 4.3, 6.8, or 36 megadaltons (MDa); several strains showed a large plasmid of 61 MDa, but it was not consistently recovered. Four C. spor...
