Crystal structure of Anthrax Lethal Factor wild-type protein complexed with an optimised peptide substrate.


Function and Biology Details

Reaction catalysed:
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.
