Interaction of the Brush-Border Hydrolases of the Human Small Intestine with Lectins

Abstract
The role of human intestinal brush border membrane hydrolases in lectin binding to the apical region of the enterocyte was investigated. The crossed-immunoelectrophoresis method was used to identify 6 hydrolases before and after interaction with 9 lectins. Three lectins (Phaseolus vulgaris, Ulex europaeus and Ricinus communis 120 agglutinins) bound the hydrolases of 5 different subjects. Helix pomatia agglutinin interacted with only 1 subject.
