Abstract
The interaction between duodenase and inhibitors of Bowman-Birk type from soybeans (BBI) and lima beans (LBI) was investigated. Duodenase was shown to interact only with antichymotrypsin site of these inhibitors. The inhibition constants of duodenase by BBI, LBI, BBI-trypsin and LBI trypsin complexes were 4, 23, 400, 600 (n)M respectively.
