comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولProcessing of Candida albicans Ece1p Is Critical for Candidalysin Maturation and Fungal Virulence
Candida albicans is an opportunistic fungal pathogen responsible for superficial and life-threatening infections in humans. During mucosal infection, C. albicans undergoes a morphological transition from yeast to invasive filamentous hyphae that secrete candidalysin, a 31-amino-acid peptide toxin required for virulence. Candidalysin damages epithelial cell plasma membranes and stimulates the ac...
متن کاملMembrane-Active Properties of an Amphitropic Peptide from the CyaA Toxin Translocation Region
The adenylate cyclase toxin CyaA is involved in the early stages of infection by Bordetella pertussis, the causative agent of whooping cough. CyaA intoxicates target cells by a direct translocation of its catalytic domain (AC) across the plasma membrane and produces supraphysiological levels of cAMP, leading to cell death. The molecular process of AC translocation remains largely unknown, howev...
متن کاملProbing Pores with Peptide Plugs: Topology of Membrane-inserted Diphtheria Toxin
Extracellular proteins are made in the cytosol and transported out of the cell. Certain proteins travel the opposite way, from the outside to the cytosol. Most of these proteins are toxins made by bacteria and plants, but evidence is accumulating that certain growth factors can do the same. Toxins that enter the cytosol can, according to current knowledge, be roughly classified into two main gr...
متن کاملInvestigating of Difference between Dioxynivalenol Fungal Toxin Pollution Level in Raw Wheat Flour and Bread
Background Deoxynivalenol (DON) is one of the most common mycotoxins found in cereal grains. Objective The purpose of this survey was determination of difference between DON fungal toxin pollution level in raw wheat flour and bread. Methods: In this In the present analytical-cross-sectional study, to determine DON level, 44 subjects were random samplings of wheat, bread and flour (Lavash and ...
