Effect of lectins from leguminous seeds on rat duodenal enterokinase activity.
Enterokinase activity from rat duodenal brush borders was assayed in vitro in the presence of purified lectins from 3 leguminous seeds. Noncompetitive inhibition of the enzyme was observed in each case. Phaseolus hemagglutinin was the most potent inhibitor among the 3 lectins tested.
