Abstract:
:A 26-kDa trypsin inhibitor with an N-terminal sequence resembling storage proteins was purified from moth beans (Phaseolus acutifolius). It dose-dependently inhibited trypsin with an IC(50) value of about 0.38 microM. It inhibited [methyl-(3)H] thymidine incorporation by lymphoma MBL2 cells with an IC(50) value of 20 microM.
