Anthrax lethal factor endopeptidase.
based on mapping to UniProt P15917
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.
-!- 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. -!- Belongs to peptidase family M34.
