Structure-function relationships in serine protease-bovine pancreatic trypsin inhibitor interaction

Protein Pept Lett. 2005 Jul;12(5):403-7. doi: 10.2174/0929866054395275.

Abstract

We report our progress in understanding the structure-function relationships for the interaction between BPTI and serine proteases. We focused on extensive mutagenesis of four crucial positions from the protease binding loop of BPTI. Selected variants were characterized by determination of association constants, stability parameters and structures of protease-inhibitor complexes.
