Anthrax protective antigen (PA) is one of the three proteins forming the anthrax toxin. It is involved in the first step of toxin entry into host cells, enabling lethal factor (LF) and oedema factor (EF) to cross to the cytosol. PA undergoes cleavage by Furin to generate PA20 and PA63. The latter, which adopts a ring-shaped heptameric assembly, shows four distinct domains. The fourth domain, a carboxy- terminal receptor-binding domain, shows an initial hairpin and helix, followed by a beta-sandwich with an immunoglobulin-like fold (this entry) [1-5].	Domain

Members of this family, which are predominantly found in anthrax toxin lethal factor, adopt a structure consisting of a core of antiparallel beta sheets and alpha helices. They form a long deep groove within the protein that anchors the 16-residue N-terminal tail of MAPKK-2 before cleavage. It has been noted that this domain resembles the ADP-ribosylating toxin from Bacillus cereus, but the active site has been modified to augment substrate recognition [1].	Domain
