adsorption of beta-glucuronidase on biopolymers is studied by the retention of the enzyme on the membrane of a concentrator with a pore diameter of 300 kDa and by native PAGE. Pectin-protein complexes (fractions PPC/CP and PPC/C) are established to increase the activity of beta-glucuronidase by 50 and 100%, respectively. There is a positive correlation between the increase of beta-glucuronidase activity in the presence of carbohydrates and enzyme adsorption on the polymers. The activity of the enzyme in the gel after electrophoresis of the PPC/+ beta-glucuronidase mixture is inversely proportional to the concentration of PPC/C in the mixture

the beta-glucuronidase forms a complex with esterase 22 in the liver. Gus colocalizes with Es22 at the endoplasmic reticulum but does not affect its RE hydrolase activity

-
beta-glucuronidase is present in every compartment of the digestive cell endo-lysosomal compartment and appears to be not necessarily membrane-bound. Enzyme is released to the digestive alveolar lumen in secretory lysosomes produced by basophilic cells and endocytosed by digestive cells
