Enzyme Function FUNCTION: Inhibitor of bovine trypsin with a Ki of 2.3 uM. Inhibits 50% of the proteolytic activity of P.rapae larvae midgut extract at a concentration of 20 ug/ml. Inhibitory activity against trypsin is reduced by 43% in the presence of the lysine modifier TBNS, but is not affected by dithiothreitol. {ECO:0000269|PubMed:19232057}.
Temperature Dependency BIOPHYSICOCHEMICAL PROPERTIES: Temperature dependence: Thermostable when incubated at pH 8.0 at temperatures between 40 and 100 degrees Celsius. {ECO:0000269|PubMed:19232057};
PH Dependency BIOPHYSICOCHEMICAL PROPERTIES: pH dependence: Stable at pH values ranging from 3.0-11.0 at 4 degrees Celsius. {ECO:0000269|PubMed:19232057};
