Crystal structure of Anthrax Lethal Factor active site mutant protein complexed with an optimised peptide substrate in the presence of zinc.
Overview
Recent events have created an urgent need for new therapeutic strategies, to treat anthrax. We have applied a mixture-based peptide library approach, to rapidly determine the optimal peptide substrate for the anthrax lethal, factor (LF), a metalloproteinase with an important role in the, pathogenesis of the disease. Using this approach we have identified, peptide analogs that inhibit the enzyme in vitro and that protect cultured, macrophages from LF-mediated cytolysis. The crystal structures of LF bound, to an optimized peptide substrate and to peptide-based inhibitors provide, a rationale for the observed selectivity and may be exploited in the, design of future generations of LF inhibitors.
