Anthrax toxin from Bacillus anthracis is a three-component toxin consisting of lethal factor (LF), edema factor (EF), and protective antigen (PA). LF and EF are the catalytic components of the toxin, whereas PA is the receptor-binding component. To identify residues of PA that are involved in interaction with the cellular receptor, two solvent-exposed loops(More)
BACKGROUND Anthrax toxin, secreted by Bacillus anthracis, consists of protective antigen (PA) and either lethal factor (LF) or edema factor (EF). PA, the receptor-binding component of the toxin, translocates LF or EF into the cytosol, where the latter proteins exert their toxic effects. We hypothesized that anthrax toxin fusion proteins could be used to(More)
Piperine, the bioactive phytochemical from black pepper (Piper nigrum L.), is a nontoxic natural compound exhibiting many physiological and pharmacological properties. They include antioxidant, anti-inflammatory, antimutagenic, antitumor, antiapoptotic, antigenotoxic, antiarthritic, antifungal, antimicrobial, antidepressant, anti-HBV, and gastro-protective(More)
