THE HISTOCHEMICAL DEMONSTRATION OF INTESTINAL BETA-D-FUCOSIDASE WITH 5-BROMO-4-CHLOROINDOLE-3-YL-BETA-D-FUCOPYRANOSIDE
Abstract
A halogen-substituted indolyl substrate for beta-D-fucosidase shows strong positive reactions in the interstitial mononuclear cells in the jejunum. This localization and the optimum pH are different from those of the closely analogous substrate for beta-D-galactosidase. The results of competitive inhibition of these substrates suggest that beta-D-fucosidase and beta-D- galactosidase are distinct but similar tissue enzymes.
