Popis: s-Glucosidases detected in the leaves and roots of the common beet,Beta vulgaris, have been demonstrated to catalyze hydrolysis of native betacyanins. A method is described for the isolation and purification of sglucosidase from the roots, which involves ammonium sulfate precipitation, DEAE-cellulose chromatography, and Sephadex gel filtration. Maximum activity of the enzyme is detected at 50°C and pH 8.0; it retains stability within the pH range from 5.1 to 9.2. In leaves, s-glucosidase is associated with chloroplast membranes; solubilization of the membranes results in enzyme inactivation.
