Webbelongs to the bovine pancreatic trypsin inhibitor (BPTI)-like superfamily. It showed a dissociation con-stant of 5.8 108 M with -chymotrypsin as measured by a BIAcore binding assay system. The isothermal ti-tration calorimetry revealed a 1:1 binding stoichiometry between this inhibitor and chymotrypsin and appar-ently no binding with trypsin. WebSubstituting the P1 position in bovine pancreatic trypsin inhibitor (BPTI) is known to heavily influence its inhibitory activity towards serine proteases. Side-chain fluorinated aliphatic amino acids have been shown to alter numerous properties of peptides and proteins and thus are of interest in the context of BPTI. In our study, we systematically …
