anthrax lethal factor endopeptidase M-CSA #641 | Lethal Factor is critical in anthrax pathogenesis, by acting as a specific protease cleaving members of the MAPKK (mitogen-activated protein kinase kinase) family at their amino termini with its commonly cleaving at the sequence BBBBxHxH, where B denotes a basic amino acid Arg or Lys and H denotes a hydrophobic amino acid. This results in signalling pathway inhibition. The catalytic domain of this enzyme is distantly related to the zinc metalloprotease family. | Defined by 5 residues: HIS:A-686GLU:A-687HIS:A-690TYR:A-728GLU:A-735 | EC: 3.4.24 (PDB Primary Data) |
