Association properties of trypsin inhibitors from lima bean
The molecular-weight properties of three purified proteinase inhibitors from lima bean were studied by using high speed sedimentation equilibrium. Two isoinhibitors [fraction I and II, nomenclature from Jones et al., (18)]do not self-associate at moderate pH and concentration (
