bovine trypsin complexed with 2-aminobenzamidazole
Overview
Improved peptide-based inhibitors of human beta tryptase were discovered using information gleaned from tripeptide library screening and structure-guided design methods, including fragment screening. Our efforts sought to improve this class of inhibitors by replacing the traditional Lys or Arg P1 element. The optimized compounds display low nanomolar potency against the mast cell target and several hundred-fold selectivity with respect to serine protease off targets. Thus, replacement of Lys/Arg at P1 in a peptide-like scaffold does not need to be accompanied by a loss in target affinity.
About this Structure
2FX6 is a Single protein structure of sequence from Bos taurus with and as ligands. Active as Trypsin, with EC number 3.4.21.4 Full crystallographic information is available from OCA.
