Anthrax lethal factor endopeptidase (EC3.4.24.83, lethal toxin) is an enzyme that catalyzes the hydrolysis of mitogen-activated protein kinase kinases. This enzyme is a component of the lethal factor produced by the bacterium Bacillus anthracis. The preferred cleavage site can be denoted by BBBBxHxH, in which B denotes a basic amino acid Arg or Lys, H denotes a hydrophobic amino acid, and x is any amino acid.[2]
