  • Title: Physical and kinetic properties of beta-glucosidase in Gaucher disease.
    Author: Karazeh A, Carroll M.
    Journal: J Inherit Metab Dis; 1983; 6(3):101-4. PubMed ID: 6422137.
    Abstract:
    Membrane-bound 'acid' beta-glucosidase of human spleen was solubilized with either sodium cholate or 'Cutscum'. The solubilized enzyme in type 1 (adult) Gaucher disease was less heat-stable than the normal enzyme, and when precipitated by ammonium sulphate it had a higher apparent molecular weight than the corresponding normal enzyme. The normal beta-glucosidase was activated by taurocholate, whereas the Gaucher enzyme was inhibited. The decrease in 'acid' beta-glucosidase activity in Gaucher disease was associated with a profound deficiency of that form of the enzyme which bound to Concanavalin A. The results are consistent with faulty processing of newly synthesized 'acid' beta-glucosidase in type 1 Gaucher disease.
