Web10. apr 2024 · The proteolytic activity of trypsin can be affected by a variety of substances, which can either stimulate or inhibit its action. Substances capable of decreasing trypsin activity include, for example, specific protease inhibitors from soybeans (such as Kunitz-type inhibitors (KSTIs) and Bowman–Birk-type inhibitors (BBIs)), cadmium, etc. [17,18]. WebSBTI contains a Kunitz trypsin inhibitor (KTI) and a Bowman-Birk inhibitor (BBI). Here, we show 1) that KTI and BBI were purified separately from soybeans; 2) that neither KTI nor …
