Crystallization of the protective antigen protein of Bacillus anthracis.
The protective antigen protein, one of the three separate proteins constituting the exotoxin system of Bacillus anthracis, has been crystallized in a form suitable for structural studies. The crystal form which is most amenable to x-ray analysis is orthorhombic, space group P2(1)2(1)2(1), a = 101.1 A, b = 95.4 A, c = 87.3 A, with one protective antigen monomer/asymmetric unit. The crystals diff...
متن کاملConstruction of a Eukaryotic Plasmid Encoding Bacillus anthracis Protective Antigen, a Candidate for DNA Vaccine
Background: DNA immunization with plasmid DNA encoding bacterial, viral, parasitic and tumor antigens has been reported to trigger protective immunity. Objective: To evaluate the use of a DNA immunization strategy for protection against anthrax, a plasmid was constructed. Methods: The partialsequence of protective antigen of Bacillus anthracis, amino acids 175-764, as a potent immunogenic targe...

Genetic diversity in the protective antigen gene of Bacillus anthracis.
Bacillus anthracis is a gram-positive spore-forming bacterium that causes the disease anthrax. The anthrax toxin contains three components, including the protective antigen (PA), which binds to eucaryotic cell surface receptors and mediates the transport of toxins into the cell. In this study, the entire 2,294-nucleotide protective antigen gene (pag) was sequenced from 26 of the most diverse B....
متن کاملActivity of the Bacillus anthracis 20 kDa protective antigen component
BACKGROUND Anthrax is caused by Bacillus anthracis that produce two exotoxins, lethal toxin and edema toxin. The lethal toxin is composed of the lethal factor (LF) complexed with the cell binding protective antigen (PA83, 83 kDa). Likewise, the edema factor (EF) binds to the PA83 to form the edema toxin. Once PA83 is bound to the host cell surface, a furin-like protease cleaves the full-length,...
