Accepted name: anthrax lethal factor endopeptidase
Reaction: Preferred amino acids around the cleavage site can be denoted BBBBxHx┼H, in which B denotes Arg or Lys, H denotes a hydrophobic amino acid, and x is any amino acid. The only known protein substrates are mitogen-activated protein (MAP) kinase kinases
Other name(s): lethal toxin
Comments: From the bacterium Bacilus anthracis that causes anthrax. One of three proteins that are collectively termed anthrax toxin. Cleaves several MAP kinase kinases near their N-termini, preventing them from phosphorylating the downstream mitogen-activated protein kinases. In peptidase family M34.
