For nearly 50 years, the Common Rule has required Institutional Review Board (IRB) oversight of federally-funded research to protect the rights and welfare of human research participants. Over time, research has changed and research studies often inv

Anthrax lethal toxin, produced by the bacterium Bacillus anthracis, is the major cause of death in animals infected with anthrax. One component of this toxin, lethal factor (LF), is suspected to be a metalloprotease, but no physiological substrates h

Clostridium septicum alpha-toxin is secreted as an inactive 46,450-Da protoxin. The protoxin is activated by proteolytic cleavage near the C terminus, which eventually causes the release of a 45-amino-acid fragment. Proteoytic activation and loss of

Before intoxication can occur, anthrax toxin protective antigen (PA), Pseudomonas exotoxin A (PE), and diphtheria toxin (DT) must be activated by proteolytic cleavage at specific amino acid sequences. Previously, it was shown that PA and DT can be ac

The alpha toxin produced by Clostridium septicum is a channel-forming protein that is an important contributor to the virulence of the organism. Chinese hamster ovary (CHO) cells are sensitive to low concentrations of the toxin, indicating that they

Several bacterial protein toxins require activation by eukaryotic proteases. Previous studies have shown that anthrax toxin protective antigen (PA), Pseudomonas exotoxin A (PE), and diphtheria toxin (DT) are cleaved by furin C-terminal to the sequenc

Pseudomonas exotoxin A (PE) binds and enters mammalian cells via the alpha 2-macroglobulin receptor/low density lipoprotein receptor-related protein (LRP). The toxin then requires proteolytic cleavage to generate an enzymatically active fragment with
