Bacillus anthrax Protective Antigen (PA)
Anthrax is a severe zoonotic infectious disease that can cause systemic infection and has a relatively high mortality rate. Bacillus anthracis, the causative agent of anthrax, produces key virulence factors, including the bacterial capsule and anthrax toxin. The anthrax toxin encoded by the pXO1 plasmid, consists of three components:
Protective antigen (PA),
Lethal factor (LF),
Edema factor (EF).
