Abstract A trypsin and chymotrypsin inhibitor from seeds ofPhaseolus vulgaris var. “Fogo na Serra” (PFSI) was purified and its complete amino acid sequence was determined using Edman degradation methods. The inhibitor was found to belong to the Bowman-Birk family of enzymatic inhibitors; it has 82 amino acid residues and a 8.985-kDa molecular mass. The PFSI/α-chymotrypsin binary complex has been modeled using the Turkey ovomucoid inhibitor third domain (OMTKY3) bound toα-chymotrypsin [Fujinagaet al. (1987),J. Mol. Biol.,195, 397–418. template. The model allowed identification of the binding surface.
