Brush border peptidases
WebHydrolysis of small peptides, like disaccharide hydrolysis, is an important function of the intestinal brush border, but little is known of the individual human peptidases. The purposes of this study were to detect all human brush border enzymes hydrolyzing dipeptides and tripeptides, identify the most discriminating substrate for each enzyme in … WebThe three peptides were susceptible to the action of brush-border peptidases. Intact LfcinB20-25 was not transported across Caco-2 whereas RWQ and WQ were both absorbed through the cell monolayer. Apparent permeability (Papp) values for absorptive transport across the monolayer were 0.7×10-8 cm s-1 (RWQ) and 3.9×10-8 cm s-1 (WQ).
