Abstract
Five BBI sequences, representing five different second reactive sites, were heterologously expressed in the yeast Pichia pastoris. The recombinant proteins demonstrated to be active against trypsin, while three of them were also active against chymotrypsin, and one against human leukocyte elastase. Comparative modeling and protein docking were used to further investigate interactions between two grass pea BBI isoforms and their target proteases. Thus two reliable 3D models have been proposed, representing two potential ternary complexes, each constituted of an inhibitor and its target enzymes. (C) 2012 Elsevier Masson SAS.
