Glycoproteins brush border plasma membrane

The complexity of the cestode tegument was discussed in Chapter 2. The brush border-plasma membrane subtending the tegument is a fluid-mosaic , consisting of proteins, glycoproteins and lipoproteins, embedded in a lipid bilayer (Fig. 2.3, p. 10). An array of membrane-bound proteins, many of which exhibit enzyme activity, is associated with the tegumental brush border plasma membrane. This important area has been comprehensively reviewed by Pappas (624). 

Alkaline phosphatase is one of the principal glycoproteins present in the microvillus plasma membrane of human placenta sixteen protein and ten glycoprotein subunits of the enzyme were detected. Purified brush-border peptidases (mol. wt. 2.8 x 10 ) from rat intestinal mucosa have been shown to...
